Wonder Girls (Korean: 원더걸스, Chinese: 奇迹女孩, Japanese: ワンダーガールズ) is a South Korean girl group, whose current line-up is Yubin, Yeeun, Sunye, Sohee and Hyelim. They are managed by their producer, the singer-songwriter Park Jin-Young under his talent agency, JYP Entertainment. They are co-managed in the United States by Creative Artists Agency. The group's name, 'Wonder Girls', comes from the idea that they are "the girls who can amaze the world". The group began their entry into the American market in 2009 as an opening act for The Jonas Brothers' World Tour, performing the English version of their hit single "Nobody". In late 2009, their song charted at number seventy-six on the Billboard Hot 100 chart, making the Wonder Girls the first South Korean group to enter the chart.
In 2010, Wonder Girls entered the Chinese market with the compilation album Wonder Girls that included Chinese language versions of "Tell Me", "Nobody" and "So Hot".
In 2012, Wonder Girls signed with DefStar Records, a subsidiary of Sony Music Japan, for their Japanese debut.
