"Royal Flush" is the debut solo single by American rapper and OutKast member Big Boi. The track was released on March 24, 2008 and it features fellow OutKast member André 3000 as well as Wu-Tang Clan member Raekwon. It was the first time the three rappers collaborated with each other in 10 years since "Skew It on the Bar-B" off of OutKast's third album Aquemini in 1998. The song was intended to be included as part of Big Boi's debut solo album Sir Lucious Left Foot: The Son of Chico Dusty, but was removed from it, due to legal complications from Big Boi resigning from Jive Records.
