Top 10 Most Watched Korean Dramas – April 2026

Most Watched Korean Drama No. 2 — 폭군의 셰프 (The Tyrant’s Chef) | tvN | 17.1%

The No. 2 most watched Korean drama of April 2026 is tvN’s 폭군의 셰프, or The Tyrant’s Chef — and its 17.1% peak rating is nothing short of historic. For a cable drama to approach 17% viewership is an extraordinary achievement that rewrites the expectations of what non-terrestrial Korean television can accomplish.

The Tyrant’s Chef blends two of Korean drama’s most beloved genres — historical palace intrigue and food culture — into a single irresistible package. The story follows a master chef navigating the dangerous politics of a royal court where food is power, loyalty is currency, and every meal could be the last. It’s a concept that sounds almost impossibly Korean — and that’s precisely why it works.

Food holds a uniquely central place in Korean cultural identity. Koreans don’t just eat — they celebrate, mourn, bond, and negotiate through food. A drama that places cuisine at the heart of its political drama speaks directly to something deeply felt in Korean daily life.

The 17.1% rating represents tvN’s highest-ever viewership for a drama in this time slot, officially cementing The Tyrant’s Chef as one of the landmark Korean dramas of the decade. International streaming rights were reportedly acquired by multiple platforms within weeks of the drama’s premiere.

Did you know? Korean food-themed dramas consistently outperform their initial ratings projections — Jewel in the Palace (Dae Jang Geum), a historical drama centered on royal cuisine, remains one of the highest-rated Korean dramas ever made with a peak rating of 57.8%.

Most Watched Korean Drama No. 3 — The Judge Returns (판사 이한영) | MBC | 13.6%

MBC claims two spots in the top three most watched Korean dramas of April 2026, with The Judge Returns (판사 이한영) securing No. 3 with a 13.6% peak rating. Starring Ji Sung — one of Korea’s most respected dramatic actors — this legal thriller has delivered exactly what fans of the genre demanded.

Ji Sung is the kind of actor whose involvement in a project functions almost as a quality guarantee for Korean audiences. His previous dramas — including the psychological thriller Kill Me, Heal Me and the legal drama Defendant — consistently achieved high ratings and critical acclaim. The Judge Returns continues this track record with a complex courtroom thriller built around a disgraced judge fighting to reclaim his reputation and deliver justice.

Korean legal dramas occupy a special place in domestic television culture. They combine the intellectual appeal of watching a brilliant mind at work with the emotional satisfaction of seeing institutional power challenged by individual integrity. It’s a formula that resonates deeply with Korean audiences who hold strong views about justice, fairness, and accountability.

The 13.6% rating places The Judge Returns firmly among April 2026’s elite dramas — a testament to both Ji Sung’s enduring star power and MBC’s continued ability to produce compelling prime-time programming.

Did you know? Ji Sung won the Grand Prize (Daesang) at the MBC Drama Awards for Kill Me, Heal Me — Korea’s highest individual honor in television drama, equivalent to a lifetime achievement moment for many actors.

Most Watched Korean Drama No. 4 — Perfect Crown (21세기 대군부인) | MBC | 13.1%

We’re now entering the top four most watched Korean dramas of April 2026 — and the competition gets fierce. MBC’s Perfect Crown (21세기 대군부인) lands at No. 4 with a 13.1% peak rating, but its cultural footprint extends far beyond what that number alone suggests.

Perfect Crown stars IU and Byun Woo-seok — two of Korea’s most beloved entertainers — in a fantasy romance that has dominated Korean social media buzz throughout 2026. By virtually every measure of online engagement, Perfect Crown ranks as the single most talked-about drama of the year so far, even while sitting at No. 4 in raw viewership.

This gap between buzz and ratings is a fascinating feature of modern Korean drama culture. Younger, digitally active viewers — the ones generating social media content, fan edits, and online discussion — often watch through streaming platforms rather than live TV. This means their viewing doesn’t fully register in traditional Nielsen ratings, creating a systematic undercount of dramas popular with younger demographics.

IU’s involvement alone guaranteed massive anticipation. She is arguably Korea’s most beloved celebrity — a rare combination of top-tier singer, acclaimed actress, and universally admired public figure whose popularity transcends any single demographic.

Did you know? IU, whose real name is Lee Ji-eun, has been named Korea’s top celebrity brand reputation index multiple times — a level of sustained public affection that very few entertainers anywhere in the world achieve.

Most Watched Korean Drama No. 5 — 언더커버 미쓰홍 (Undercover Miss Hong) | tvN | 11.1%

tvN’s 언더커버 미쓰홍, or Undercover Miss Hong, claims No. 5 with an impressive 11.1% peak rating — and what makes this achievement especially remarkable is the consistency behind it. This drama recorded three consecutive weeks of self-best rating records throughout April 2026, signaling genuine audience momentum rather than a one-week spike.

tvN is Korea’s leading cable and streaming drama network, known for producing critically acclaimed hits like Crash Landing on You, My Mister, and Vincenzo. Achieving 11.1% on cable is the equivalent of a much higher rating on terrestrial broadcast — the audience base is smaller but far more actively engaged.

Undercover Miss Hong follows a sharp, unconventional female protagonist navigating a world of deception — a character archetype that tvN has mastered over the years. Korean audiences respond powerfully to heroines who are clever, resilient, and slightly unpredictable, and this drama delivers exactly that energy.

The three-week consecutive growth pattern is particularly significant. It indicates strong word-of-mouth, positive social media sentiment, and the kind of organic audience building that sustains a drama well beyond its broadcast run on international platforms.

Did you know? tvN is owned by CJ ENM, the same conglomerate behind the Mnet music channel and the MAMA Awards — giving Korean drama and K-pop a shared corporate ecosystem that amplifies both industries globally.

Most Watched Korean Drama No. 6 — Phantom Lawyer (유령 변호사) | SBS | 10.0%

SBS enters our most watched Korean dramas ranking at No. 6 with Phantom Lawyer (유령 변호사), a weekend mini-series delivering a sharp 10.0% peak rating. Legal thrillers have been a perennial favorite with Korean audiences, and Phantom Lawyer demonstrates that the genre still has plenty of firepower in 2026.

The premise follows a brilliant lawyer with a secret — a supernatural ability to communicate with the dead — using this gift to solve cases that conventional law cannot crack. It’s a high-concept blend of legal procedural and fantasy elements that Korean drama writers execute with particular skill.

SBS has long been known for polished weekend dramas that balance strong plotlines with high production values. Phantom Lawyer continues this tradition, delivering the kind of binge-worthy episodic structure that works equally well for live Korean viewers and international streamers discovering it weeks later.

The drama has performed especially strongly among Korean viewers in their 30s and 40s — a demographic that advertisers prize highly, making it one of April 2026’s most commercially valuable dramas despite not topping the ratings chart.

Did you know? SBS weekend dramas consistently attract Korea’s highest advertising rates per minute, often exceeding those of cable competitors with similar or even higher ratings.

Most Watched Korean Drama No. 7 — 기쁜 우리 좋은 날 (Our Happy Days) | KBS1 | 10.1%

Here’s a entry that will genuinely surprise most international K-drama fans. KBS1’s daily drama 기쁜 우리 좋은 날, or Our Happy Days, achieved a remarkable 10.1% peak rating — placing it above several prime-time weekend dramas on this list.

KBS1 is Korea’s most traditional broadcast channel, home to news, documentaries, and family-oriented programming. Its daily drama slot has cultivated one of Korean television’s most loyal and consistent audiences — older viewers who tune in every single weekday without fail. These viewers don’t chase trending shows or read drama reviews online. They simply watch, every day, out of habit and genuine affection for the format.

Our Happy Days delivers exactly what this audience wants: warm family relationships, relatable everyday struggles, and the quiet reassurance that good people are rewarded in the end. It’s the televisual equivalent of comfort food — and in April 2026, Korean audiences are consuming it in significant numbers.

This drama’s 10.1% rating is a powerful reminder that the loudest voices in K-drama fandom online do not necessarily represent the largest audience actually watching Korean television.

Did you know? KBS1’s daily drama slot has maintained consistent double-digit ratings for decades, making it one of the most reliable advertising environments in Korean broadcasting.

Most Watched Korean Drama No. 8 — 은애하는 도적님아 (My Dear Thief) | KBS2 | 7.7%

At No. 8 sits KBS2’s sageuk romance 은애하는 도적님아, loosely translated as My Dear Thief. With a 7.7% peak rating, this historical romance drama has become one of April 2026’s most talked-about entries in the traditional Korean drama genre.

Sageuk — Korean historical dramas — have experienced a powerful revival in recent years. After a period when modern romcoms and dark thrillers dominated ratings, Korean audiences have returned to the comfort of elaborate period costumes, Joseon-era court intrigue, and sweeping romantic storylines set against stunning historical backdrops.

My Dear Thief blends the classic sageuk romance formula with a charming anti-hero lead — a skilled thief with a hidden noble heart — creating exactly the kind of wish-fulfillment narrative that Korean audiences adore. The chemistry between the leads and the lush production design have generated significant buzz on Korean social media throughout April.

For international viewers, sageuk dramas offer a fascinating window into Korean history, fashion, and social hierarchy. Many global K-drama fans cite historical dramas as their entry point into Korean culture more broadly.

Did you know? Korean sageuk dramas are so culturally influential that they regularly spark tourism booms at filming locations, with fans traveling from across Asia to visit the historical villages and palaces featured on screen.

Most Watched Korean Drama No. 9 — 붉은 진주 (Red Pearl) | KBS2 | 7.5%

KBS2’s evening daily drama 붉은 진주, or Red Pearl, holds the No. 9 spot with a 7.5% peak rating. Like its stablemate at No. 10, Red Pearl represents the enduring power of the Korean daily drama format — a genre that international audiences rarely encounter but that consistently delivers some of Korean television’s most dedicated viewership.

Red Pearl airs in KBS2’s coveted weekday evening slot, competing directly with other network dailies for the attention of viewers settling in after dinner. The drama follows the classic Korean melodrama formula — family conflicts, hidden identities, romantic entanglements, and slow-burning revenge — executed with the kind of polish that KBS brings to its flagship productions.

What makes KBS daily dramas particularly notable is their cross-generational appeal. Grandparents, parents, and adult children often watch together, making these shows genuine family viewing events in a way that edgier cable dramas rarely achieve.

For global K-drama fans accustomed to the fast-paced, cinematic style of Netflix productions, watching a Korean daily drama is a genuinely different experience — slower, warmer, and deeply rooted in traditional Korean family dynamics.

Did you know? KBS (Korean Broadcasting System) is Korea’s national public broadcaster, funded partly by a mandatory TV license fee collected from all Korean households — similar to the BBC in the UK.

Most Watched Korean Drama No. 10 — 첫 번째 남자 (The First Man) | MBC | 5.8%

Rounding out our list of the most watched Korean dramas in April 2026 is MBC’s daily series 첫 번째 남자, or The First Man. Don’t let the 5.8% peak rating fool you — daily dramas in Korea air five times a week, accumulating loyal audiences that weekly dramas can only dream about.

Daily dramas occupy a unique space in Korean television culture. They air in the early evening slot, targeting viewers who come home from work and settle into a familiar, comforting storyline. The format demands consistency over spectacle — characters develop slowly, relationships build over months, and viewers invest deeply in long-running arcs.

The First Man has built its audience through steady momentum, showing consistent rating increases week over week throughout April 2026. This upward trajectory is often a stronger signal of genuine audience engagement than a single spike driven by a marketing campaign.

For foreign viewers, daily dramas are rarely available on international streaming platforms — making this entire genre almost invisible to the global K-drama audience. Yet they represent some of the most-watched content in Korea by total viewing hours.

Did you know? Korean daily dramas typically run for 100–120 episodes, meaning dedicated viewers spend more total hours with these shows than with any prestige weekend drama.
