Wonder Girls (Hangul: 원더걸스) was a South Korean girl group which consisted of Yeeun (HA:TFELT), Yubin (유빈), Hyerim (혜림) and Sunmi (선미) in its final lineup. Their producer and manager was singer-songwriter Park Jin-Young, and the Wonder Girls were signed to his talent agency JYP Entertainment. Each of the five original members were selected through auditions.

Debuting in early 2007, they became popular in the fall of that year with the song "Tell Me." They have scored five consecutive #1 hit singles: "Tell Me", "So Hot", "Nobody", "2 Different Tears" and "Be My Baby". In 2008, they won two "Artist of the Year" awards.

The group began their entry into the American market in 2009, with lead single "Nobody"; the single became the first song by a Korean group to enter the Billboard Hot 100. They are co-managed in the United States by JYP Entertainment and Jonas Group. They managed to place 4th with "Nobody" on the Canadian single charts for the past 2 weeks of March 2011.

Former member Hyuna (현아) left in June '07 due to health problems. She later joined girl group 4minute which disbanded in 2016. At the end of 2009, Sunmi (선미) left to continue her education. She was replaced with trainee Hyelim. She later on returned to singing with the release of her hit-single "24시간이 모자라" in 2013. With the announcement of Wonder Girls' comeback in 2015, Sunmi rejoined the group. Later in 2015, Sunye (선예) and Sohee (소희) officially withdrew from the group.

On 26 January 2017, Wonder Girls officially disbanded after members Sunmi and Yeeun decided not to renew their contracts.
