Back on My B.S. is the eighth studio album by American rapper Busta Rhymes. It was released on May 19, 2009 through Flipmode and Universal Motown.

The album was originally going to be called Before Hell Freezes Over, but went through several name changes (including Back on My Bullshit, Blessed and B.O.M.B.) before being finalized as Back on My B.S.. The release date changed many times, mostly due to Busta Rhymes' release from Aftermath Entertainment and Interscope Records. The album was originally supposed to come out as early as December 4, 2007 but went through many projected release dates before an official release date of May 19, 2009.
