Han Hyo-joo, born on February 22, 1987, as Han Ji-yeong, is a celebrated South Korean actress who has risen to become one of the most prominent Hallyu stars of her generation. She first captured widespread public attention through the back-to-back successes of the television dramas Brilliant Legacy in 2009 and Dong Yi in 2010, both of which achieved massive viewership ratings in South Korea and cemented her status as a household name. This early momentum propelled her into the upper echelons of the entertainment industry, and she has since been featured multiple times on Forbes magazine's Korea Power Celebrity 40 list since 2011, while also serving as the commercial face for major Korean brands including Samsung, LG, and Lotte.

Han's career is marked by a remarkable versatility across both television and film. On the small screen, she continued to build her legacy with the romantic fantasy drama W in 2016, a hit series set in a parallel universe that showcased her ability to blend romance with genre-bending storytelling. She later starred in the apocalyptic zombie thriller Happiness in 2021, further demonstrating her range. In 2023, she took on a leading role in the high-profile supernatural action series Moving, which became the most watched Korean original series on Disney+ globally and on Hulu in the United States, with a second season currently in production. The pan-Asian and global popularity of these works have firmly established Han as a top-tier Hallyu star, and she has also served as a brand ambassador for luxury fashion houses such as Chanel, Louis Vuitton, Burberry, Ferragamo, Brunello Cucinelli, and Tiffany & Co.

In addition to her prolific television work, Han is a highly respected leading actress in the Korean film industry. She has gained critical acclaim across a wide range of genres, from melodramas and romantic comedies to large-scale action movies and crime thrillers. Her notable film roles include My Boss, My Teacher in 2006, the melodrama Always in 2011, the historical epic Masquerade in 2012, the disaster film Love 911 in 2012, the crime thriller Cold Eyes in 2013, and the romantic comedy The Beauty Inside in 2015. In 2021, the Korean Film Council (KOFIC) selected Han as one of the 200 Korean actors who best represent the present and future of Korea's movie scene, an honor aimed at introducing them to professionals in the global film industry.

The recipient of numerous accolades, Han has achieved a rare and prestigious feat by winning Best Actress honors at all three of Korea's most esteemed award ceremonies. She won the Baeksang Arts Award for her performance as the titular character in Dong Yi, the Blue Dragon Film Award for her work in Cold Eyes, and the Grand Bell Award, the Korean equivalent of the Academy Awards, for her role in Moving. Beyond her acting, she is known for her philanthropic efforts and her dedication to her craft, maintaining a reputation as one of the most talented and bankable stars in the Korean entertainment landscape.
