"Mr. Taxi" is a pop song recorded by Girls' Generation. It is the twelfth track from their album The Boys and the repackaged edition of their album Mr. Taxi.
The song was released for the first time on the single "Mr. Taxi/Run Devil Run" on April 27, 2011 and was later added on their first full Japanese album Girls' Generation on June 1, 2011.
The teaser video for the song was released on April 22, 2011 while the dance version was released on April 25, 2011 and the music video was released on April 28, 2011.

The dance version of the video begins with the girls dressed in yellow taxi driver outfits in silhouette in front of a screen that flashes words and patterns in blue lighting. At the beginning of Tiffany's third line, it changes to the girls being dressed in black outfits (with multicolored piping for each girl), and dancing in front of a multicolored map of the world with alternating shots of the girls in their yellow outfits. There is a dance break performed by Hyoyeon. The bridge is performed by Yuri, Sunny, Sooyoung, Jessica, Tiffany and Taeyeon, after which there are more alternating shots between the two scenes (yellow and black outfits), ending with the girls freezing in silhouette in their yellow uniforms as the light fades out.
