Antwan André Patton (born February 1, 1975), known professionally as Big Boi, is an American rapper, record producer, and actor. Born in Savannah, Georgia and raised in Atlanta, he is best known for being one half of the Southern hip hop duo Outkast, which he formed in 1992 alongside fellow Atlanta-based rapper André 3000.

As part of Outkast, the duo's six studio albums were each met with critical and commercial success, spawning hit songs including "Ms. Jackson", "Roses", "So Fresh, So Clean" and "Elevators (Me & You)", among others. Their fifth, a double album titled Speakerboxxx/The Love Below (2003), won three Grammy Awards and contained a solo single performed by Patton: "The Way You Move" (featuring Sleepy Brown), which peaked atop the Billboard Hot 100 and was named the 22nd most successful song of the 2000s decade by Billboard. After the duo split in 2007, he promptly pursued a solo career and signed with Def Jam Recordings to release his debut studio album, Sir Lucious Left Foot: The Son of Chico Dusty (2010). Met with continued success, it peaked at number three on the Billboard 200 and was followed by his second and third albums, Vicious Lies and Dangerous Rumors (2012) and Boomiverse (2017)—both of which were met with continued praise and moderate commercial performance.

His spin-off projects include a collaborative recording outfit with Phantogram, with whom he has released one extended play (2015). He formed the now-defunct supergroup Purple Ribbon All-Stars in 2004, which included Janelle Monáe, Bubba Sparxxx, and Killer Mike; the group released two albums until disbanding in 2007.
