The 10 Most Famous K-Dramas of the Last 10 Years (2016–2026)

The 10 Most Famous K-Dramas of the Last 10 Years (2016–2026)

If you've spent any time on social media over the past decade, you already know Korean dramas have gone from a niche hobby to a full-blown global obsession. What used to be something only dedicated fans tracked down on niche streaming sites is now front-page content on Netflix, trending on Twitter within hours of release, and dominating watercooler conversations from Seoul to São Paulo.

So which shows actually earned that spotlight? Below is a rundown of the ten K-dramas from 2016 through 2026 that left the biggest mark — whether through record-breaking viewership, cultural impact, or simply refusing to leave anyone's mind months after the finale aired.

1. Squid Game (2021)

There's no getting around it — Squid Game is the drama that changed everything. Hwang Dong-hyuk's brutal survival thriller, in which cash-strapped contestants play deadly versions of childhood games for a life-changing prize, became Netflix's most-watched series ever at the time of its release.

It turned green tracksuits and pink guards into Halloween costumes worldwide, made Lee Jung-jae a household name outside Korea, and proved that a subtitled Korean show could out-perform anything Hollywood was putting out that year. Love it or find it too grim for your taste, Squid Game is the single biggest reason K-dramas broke into the mainstream Western conversation.

2. Crash Landing on You (2019–2020)

Few dramas have romance fans as devoted as this one. The premise sounds almost too wild to work — a South Korean heiress paraglides off course and lands in North Korea, where she falls for the army officer sworn to protect her — yet the chemistry between Hyun Bin and Son Ye-jin turned it into a genuine phenomenon.

The show became one of the highest-rated cable dramas in Korean television history, and the off-screen romance between its two leads (they later married) only added to its legend. If you ask a casual K-drama fan for one recommendation, this is often the answer.

3. Goblin (2016–2017)

Ten years on, Goblin still gets brought up as a turning point for the entire industry. Gong Yoo stars as an immortal "goblin" cursed to live forever until he finds his human bride, and the show blended fantasy, dark humor, and heartbreak in a way that felt genuinely new at the time.

Its soundtrack became a chart phenomenon on its own, its fashion choices influenced trends for years, and it helped kickstart the wave of high-production-value fantasy romance that dominated the years that followed.

4. Kingdom (2019–2020)

Zombies meet the Joseon dynasty. Kingdom took a familiar horror trope, dressed it in stunning period costumes, and used it to sneak in sharp political commentary about power and corruption.

It was one of Netflix's first big K-drama originals and proved the platform's international audience had an appetite for Korean horror and historical drama that went well beyond romance. The show's atmospheric visuals and genuinely tense pacing still hold up as some of the best genre work to come out of Korea.

5. It's Okay to Not Be Okay (2020)

This one struck a nerve with viewers well beyond Korea for how openly it dealt with mental health, trauma, and emotional healing — topics K-dramas historically tiptoed around. Kim Soo-hyun and Seo Ye-ji's performances, paired with genuinely gorgeous cinematography inspired by fairy-tale illustrations, made it a critical and streaming favorite.

It's frequently cited as one of the shows that helped shift the genre toward more honest, less sanitized storytelling.

6. Extraordinary Attorney Woo (2022)

Park Eun-bin's performance as an autistic lawyer navigating her first job at a top law firm turned this show into a surprise global hit. It handled its subject matter with a rare mix of warmth and nuance, avoiding easy stereotypes while still being funny, moving, and occasionally whimsical (whales included).

The drama sparked real conversations about neurodivergence and workplace inclusion in Korea and abroad, and it's a strong example of how a "smaller" concept can outshine bigger-budget competition.

7. The Glory (2022–2023)

Song Hye-kyo's comeback vehicle is one of the coldest, most meticulously plotted revenge stories the genre has produced. It follows a woman methodically dismantling the lives of the classmates who tormented her in school, and its unflinching look at school violence sparked serious public discussion in Korea about bullying and accountability.

Split into two parts and released a few months apart, it became one of Netflix's biggest non-English titles and reignited global interest in the "elegant revenge" subgenre.

8. Reply 1988 (2015–2016)

Technically premiering right at the edge of our ten-year window, Reply 1988 is still essential viewing and regularly tops "best K-drama ever" lists. Set in a tight-knit Seoul neighborhood in the late 1980s, it's less about plot twists and more about nostalgia, family, and friendship — and it's frequently credited with one of the most satisfying, earned endings in the genre's history.

If you want to understand why K-dramas can make people cry over something as simple as a family dinner scene, this is the show that explains it.

9. Business Proposal (2022)

Not every entry on this list has to be prestige television, and Business Proposal is proof that a well-executed, purely fun rom-com can be just as culturally significant.

Based on a hit webtoon, the story of a fake dating arrangement gone sideways became one of the most-watched non-English titles on Netflix during its run and introduced a new wave of viewers to the rom-com side of K-dramas, especially younger audiences discovering the genre for the first time through streaming.

10. What's Wrong with Secretary Kim (2018)

A genuine sleeper hit that has aged into something close to a modern classic. Park Seo-joon and Park Min-young's office rom-com about a boss realizing he's in love with the secretary he's taken for granted has consistently ranked among the most-rated K-dramas on platforms like Viki years after it aired.

It's the kind of comfort-watch that keeps finding new fans, proof that a great rom-com never really goes out of style.

Final Thoughts

What's striking about this list is how different these ten shows are from each other — brutal survival horror sitting next to cozy neighborhood nostalgia, fantasy romance next to hard-hitting legal drama.

That range is exactly why the Hallyu wave has had such staying power over the last decade: there's genuinely something for every kind of viewer.

If you're new to K-dramas, any one of these ten is a safe place to start. And if you've already seen them all, well, that's what the next ten years of Korean television are for.
