"Go Girl" is a song co-written and performed by American R&B singer Ciara. The song was released as the lead single, for her third studio album Fantasy Ride, however it was only included on the Japan version of the album. The track is a female empowerment anthem that preaches control, featuring semi-auto-tune vocals and a mid-tempo beat.

"Go Girl" was released worldwide to digital outlets on September 26, 2008 and sent to radio stations on September 30, 2008. The song garnered mixed reviews from music critics. The single made Vibe's 80 Best Songs of 08' list, at the number 69. The Official Remix of the song features American rapper, Gorilla Zoe.

The single was also used as the intro for Ciara's supporting act set, for Britney Spears world tour The Circus Starring Britney Spears.

"Go Girl" was originally written by T-Pain and rewritten with Ciara. Also, it features T-Pain. According to BET's Access Granted, LaFace A&R executive Mark Pitts asked T-Pain to write and produce tracks for Ciara's third album Fantasy Ride. T-Pain had several top ten hits and collaborated with Chris Brown on his U.S. number one single, "Kiss Kiss". "I enjoyed the whole process" said Ciara, while on the "Go Girl" music video set. T-Pain said on the video set, "The record came together basically with me and Ciara working for days in the studio, and we got pressured to ... make a song." It is the only song they finished recording.

The demo recording of "Go Girl" titled, "Hood Girl" leaked on the internet in mid-August 2008. It contains alternate lyrics and limits T-Pain's vocals.

In April 2009, when the track listing for Fantasy Ride was released through online retailers, it revealed that the track will not be featured on the Standard version of the album, but the music video will be featured on limited edition of the Fantasy Ride. It was, however, featured on the B-side to the physical release of the Love Sex Magic single and on the Japanese editions of Fantasy Ride as a bonus track.
