"I've Got to Have It" is a song by American rappers Jermaine Dupri and Nas featuring American singer Monica, released by So So Def Recordings and Columbia Records on May 2, 2000 as the lead single for the soundtrack to the comedy film Big Momma's House (2000). Its production, helmed by Dupri, samples English singer Peter Gabriel's 1986 song "Sledgehammer".
"I've Got to Have It" peaked at number 68 on the Hot R&B/Hip-Hop Songs chart, but failed to enter the Billboard Hot 100.
Dupri, Nas, and Monica teamed with director Dave Meyers to shoot a video for the song, which depicts them hosting a party under the watchful eye of Martin Lawrence in his role as Big Momma.
