"Ha" is a 1998 single by rapper Juvenile, from his third album 400 Degreez. It was produced by Mannie Fresh. This song, along with Juvenile's "Back That Azz Up" and B.G.'s "Bling Bling" was responsible for taking Cash Money Records from a small local label in New Orleans to the pop mainstream. The song is notable for its unique style of rapping, with every line except the chorus ending with "ha". The chorus to the song includes a line taken from the earlier Juvenile single "Solja Rags".
"When Jay-Z called – "I wanna get on the remix to 'Ha'" – I knew I'd arrived. That was unheard of at the time. That catapulted Cash Money even further, when that song hit the airwaves, people were like, damn, Jay-Z is on that song and he’s doing the 'Ha' thing."

Two remixes were recorded and also included on 400 Degreez. The first had a different beat and lyrics, and featured Juvenile's fellow Hot Boys members B.G., Lil Wayne, and Turk. The second had the same beat but different lyrics and featured a new verse from New York rapper Jay-Z. The second remix was not planned until Jay Z himself personally contacted Baby and requested to be included on the remix. Jay-Z was the only guest on the album not signed to Cash Money Records.
