"Round Up" is a song by American rapper Lady May, featuring American R&B singer Blu Cantrell. Released as a single in June 2002, the song was supposed to be the lead single from May's debut album, May Day, but the album has never been released. The single performed moderately in the U.S. urban market, peaking at number ninety-three on Billboard's Hot R&B/Hip-Hop Songs the week of July 27, 2002. "Round Up" never appeared on any albums except on non-U.S. pressings of Cantrell's second studio album, Bittersweet, released in 2003.

The video, directed by Director X and shot in the Mojave Desert, is a remake of the 1991 road movie Thelma & Louise, and features May and Cantrell stealing money from a gas station, sleeping in a motel, running away from police, and driving a helicopter at the end of the video to escape from the local police.
