Patrick Stephen Houston (better known as Project Pat) is an American rapper originating from Memphis, Tennessee. He is the older brother of Juicy J, co-founder of the Three 6 Mafia.

Project Pat broke onto the mainstream scene after re-emerging as a recording artist in 1999 with the album Ghetty Green & its singles. The following year, he provided the hook for Three 6 Mafia's song Sippin' on Some Sizzurp and released his breakthrough album Mista Don't Play: Everythangs Workin', the most successful album ever for an independent artist on the Hypnotize Minds label, the next year. In 2001, he was arrested for parole violation after a pair of revolvers were discovered in his vehicle during a traffic stop. That March, he was sentenced to four years in prison on two counts of a felon in possession of a firearm. His third album Layin' Da Smack Down was released during Pat's incarceration. In late 2009, Project Pat began attempting to start up a new record label called D-Brady Ent.
