"Ikuze! Kaitō Shōjo" (行くぜっ!怪盗少女^?, lit. "Let's Go! Thief Girls") is the debut major-label single by the Japanese girl group Momoiro Clover, released in Japan through Universal J on May 5, 2010. It reached third place on the Oricon charts. The dance routine for the song incorporates intense acrobatics, including a "shrimp jump", cartwheels and a leapfrog.

The single was released on May 5, 2010 in 7 versions: Regular Edition and one limited edition for each member: Limited Edition A, Limited Edition B, C, D, E, and F. Each limited edition has a different member on the cover. The single debuted at the 1st place in the Oricon Daily singles Chart and at the 3rd place in the Oricon Weekly Singles Chart, selling in that first week 22,537 copies.

On September 26, 2012, Momoiro Clover's already former label Universal J re-released the single under the title of "Ikuze! Kaitō Shōjo (Special Edition)" (行くぜっ！怪盗少女～Special Edition～^?). The 2012 re-release was a repackage of the original version. It only had one version, with the cover of the original Regular Edition, but it included a DVD with the original music video for the song "Ikuze! Kaitō Shōjo". The re-release debuted at number 6 in the Oricon daily singles chart and at number 7 for the week.

In some scenes of the music video, the members appear wearing costumes of a maid, a nurse, a policewoman, etc. The dance routine for the song incorporates intense acrobatics. One of the highlights of the video is Kanako Momota performing a so-called "shrimp jump" (えびぞり^?) (an upward jump with an arched back and both legs bent backwards, called a sheep jump in gymnastics). The jump is also the highlight of the group's live concerts. Also, at live performances of the song Shiori Tamai and Momoka Ariyasu do cartwheels and Kanako Momota performs a handspring.
