Who were Wonder Girls? Members and debut, "Tell Me" and "Nobody," the Billboard Hot 100, the 2017 disbandment — and work after the group

JYP's first girl group debuted with "Irony" in 2007. This guide follows the changes from the original Sunye, Yeeun, Sunmi, Sohee and Hyuna line-up to the addition of Yubin and Hyerim, the No. 76 Hot 100 entry for "Nobody," the 2015 band album Reboot, the 2017 disbandment and the members' later work.

Wonder Girls were the first girl group of JYP Entertainment, the company founded by singer-producer J.Y. Park. They debuted in February 2007 with the single "Irony" and closed ten years of activity with the farewell single "Draw Me" on February 10, 2017. The debut line-up was Sunye, Yeeun, Sunmi, Sohee and Hyuna; Hyuna left and Yubin joined in 2007, Sunmi paused group activities and Hyerim joined in 2010, and in 2015 Sunye and Sohee departed while Sunmi returned, leaving a four-piece band of Yeeun, Yubin, Sunmi and Hyerim. "Tell Me" (2007) and "Nobody" (2008) were back-to-back hits, and in October 2009 "Nobody" became the first song by a Korean act to enter the US Billboard Hot 100, at No. 76.

On January 26, 2017 JYP announced the group's disbandment, and Yeeun and Sunmi left the company. Yubin, Sunye, Sohee and Hyerim discussed the possibility of a reunion in a YouTube video in July 2025. Sunmi released "Forever July" on July 15, 2026, while Sohee said in a video released in March 2026 that she was focusing on acting.

Wonder Girls were a JYP Entertainment girl group discovered and produced by J.Y. Park, debuting in February 2007 with the single "Irony." The original five were Sunye, Yeeun, Sunmi, Sohee and Hyuna.

When and how did they chart on the Billboard Hot 100?

In 2009 the group announced a push into the US market and released an English version of "Nobody." On October 22, 2009 Yonhap reported that "Nobody" had entered the Billboard Hot 100, the main US singles chart, at No. 76 — the first entry on that chart by a Korean act. The Korea Herald wrote in 2018 that No. 76 remained the highest Hot 100 position for a K-pop girl group until Blackpink surpassed it, and a 2024 Herald column again recorded Wonder Girls as the first K-pop group to chart on the Hot 100. Looking back in 2015, Newsis noted that the group's US activities afterward were hampered by the financial crisis, among other factors.

Will they reunite?

The reunion discussion reported by Xportsnews on July 7, 2025 did not include a specific schedule for group activities. On Yubin's YouTube show in July 2025, Yubin said that watching 2NE1's concert made her imagine Wonder Girls on stage again, and Sohee said that "if everything lines up, we'd have fun doing it." Those were expressions of the members' wishes, not an announcement of plans.

Who played which instrument in the band?

At the 2015 Reboot showcase, Yeeun played keyboards, Yubin drums, Sunmi bass and Hyerim guitar. Yeeun said the band grew out of the members learning instruments and playing together. The album contained 12 tracks, and the members participated in writing the songs other than the lead single, "I Feel You."
