With the explosive popularity of Korean dramas worldwide, streaming platforms have been flooded with a staggering variety of K-dramas in every genre—romance, comedy, thriller, historical, fantasy, and everything in between. While this boom is exciting, it can be overwhelming for new or casual viewers to figure out where to start. If you’re wondering which series are truly worth your time, this list of 25 must-watch Korean dramas will guide you to the very best the genre has to offer.
A Genre for Every Mood
One of the strongest features of K-dramas is their versatility. Whether you’re into heart-wrenching melodramas or laugh-out-loud comedies, there’s a title that will hook you. Series like The Glory (2022) dive into intense revenge and psychological drama, with Song Hye-kyo delivering a powerhouse performance as a woman confronting her past tormentors. On the lighter end, Mr. Queen (2020) adds a comedic twist to time-travel and body-swap tropes, as a modern-day chef finds himself trapped in the body of a Joseon-era queen.
Romance continues to be a core of many K-dramas. Crash Landing on You (2019) explores a forbidden cross-border love story between a South Korean heiress and a North Korean soldier, blending suspense, humor, and touching emotion in equal measure. Meanwhile, Reply 1988 (2015) brings a nostalgic look at youth, friendship, and first love in a Seoul neighborhood during the late 1980s.
Emotional Rollercoasters and High Stakes
Some of the best Korean dramas succeed because they aren’t afraid to dig into emotionally charged narratives. Shows like While You Were Sleeping (2017) and Healer (2014) combine romance with suspense and supernatural elements, offering plot twists and poignant relationships that keep viewers glued to the screen.
For fans of mystery and crime, Signal (2016) is a landmark title. Based on real unsolved cases in Korea, it uses time-travel communication between two detectives to deliver one of the most gripping, critically acclaimed thrillers in K-drama history.
Not to be outdone, Itaewon Class (2020) pairs a tale of revenge with underdog entrepreneurship, while boldly addressing societal issues like discrimination and privilege. And of course, Squid Game (2021) shattered global records with its brutal, high-stakes depiction of capitalism and survival.
Historical Hits and Fantastical Worlds
If you’re drawn to elaborate costumes, royal intrigue, and sweeping historical settings, K-dramas like The King’s Affection (2021), Moon Lovers: Scarlet Heart Ryeo (2016), and Mr. Sunshine (2018) are absolute standouts. These series combine beautifully shot period details with emotional depth and layered storytelling.
On the fantasy side, Alchemy of Souls (2022) shines with imaginative world-building and romantic tension. Fans of supernatural and mythological lore will also enjoy Gu Family Book (2013), which introduces gumiho legends in a love story that spans generations.
Even older titles like Full House (2004) and Princess Hours (2006) remain beloved classics, introducing now-familiar tropes like contract marriages and royal makeovers, with charm that still holds up today.
