Hazen Street (also known as Hazen St.) is a supergroup that formed in early 2004.

The band features Freddy Cricien and Hoya of New York hardcore band Madball; Toby Morse of hardcore band H₂O; David Kennedy of alternative rock band Box Car Racer, hardcore punk band Over My Dead Body, and later neo-progressive rock band Angels & Airwaves; and Mackie of The Cro-Mags & Bad Brains. Chad Gilbert of Shai Hulud and later New Found Glory co-wrote and helped record every song on the album, but he was soon dismissed from Hazen Street by New Found Glory's record label due to a contract dispute. He was replaced by Mitts of Madball.
