"Pumps and a Bump" is a song by American rapper MC Hammer from his fifth album, The Funky Headhunter (1994).

"Pumps and a Bump" was the first single off The Funky Headhunter, which represented a departure from Hammer's previous pop image.

In 2010, American Idol contestant Larry Platt performed his own song titled "Pants on the Ground", which Entertainment Weekly claimed sounded similar to "Pumps and a Bump".
