504 Boyz were an American hip hop group from New Orleans, Louisiana, named for the New Orleans area code.

The original 504 Boyz, Master P (as "Nino Brown"), Mystikal (as "G. Money"), Silkk the Shocker (as "Vito"), C-Murder, and Krazy, released their first album, Goodfellas, in 2000. It included the hit single "Wobble Wobble", a "bounce-flavored song" which peaked at #17 in the U.S.

In 2002, new members were introduced as part of the New No Limit rebrand. Choppa, Currensy, Afficial, and T-Bo were on the 2002 album Ballers, which produced a minor hit single Tight Whips. C-Murder was arrested for murdering a fan in 2001.

After Hurricane Katrina hit New Orleans in 2005, 504 Boyz released a benefit compilation We Gon Bounce Back, their third and final album.
