Im Yoon-ah (; born May 30, 1990), also known mononymously as Yoona, is a South Korean singer and actress. After training for five years, she debuted as a member of girl group Girls' Generation (and later its subgroup Girls' Generation-Oh!GG) in August 2007, which went on to become one of the best-selling artists in South Korea and one of South Korea's most widely known girl groups worldwide. Apart from her group's activities, Im has participated in various Korean drama, notably You Are My Destiny (2008), which marked her career breakthrough and earned her the Best New Actress award at the 45th Baeksang Arts Awards.
Im has since achieved further public attention and acting acclaim with a variety of role-types in The K2 (2016), Big Mouth (2022), and King the Land (2023). Her film work includes Confidential Assignment (2017), Exit (2019), her first leading role, and (2022), all of which are among the highest-grossing films in South Korea.

In 2025, Im starred in the wildly popular Bon Appétit, Your Majesty, where she was cast as a three star Michelin chef who was transported back in time to become the chief royal cook for a Joseon king.
The success of Im's music and acting careers have led her to various CF deals, notably long-term collaborator Innisfree, and have established her as a top Korean idol-actress of Korean Wave.
Im graduated from Daeyoung High School in 2009. She went on to major in Theatre studies and graduated from Dongguk University in February 2015, receiving a lifetime achievement award at the graduation ceremony.

Im played two characters: Yun-hee of the 70s and Ha-na of modern times. Although the drama scored low domestic viewership and was criticized for its failure to relate to the viewers, Im's acting received positive reviews. Yoon Ga-ee of OSEN wrote: "The speed at which her acting is improving is blinding. She has matured to the point where you want to ask, 'When did her acting get so good?' The criticism that trailed behind her during Cinderella Man is now nowhere to be found." Choi In-kyung of Hankook Ilbo said her acting was continuously improving and "Yoona is completely immersed in her character and has now become 'Hana' herself." The drama garnered much positive overseas interest and was sold to Japan for $10 million, the second highest price for a KBS drama at the time, partly due to Im's popularity.

In September 2016, Im starred in tvN's action thriller The K2. Tired of being typecast with a candy-like image and having always been burdened by the idol-actress prejudice, Im cast away the public perception and focused on the role as her "personal challenge." Her effort gained positive viewers' recognition, and earned her acting acclaim from critics.
