A moonsault, moonsault press, or back flip splash is a professional wrestling aerial technique. Much of its popularity in American wrestling is attributed to The Great Muta, despite it being used in North America by "Leaping" Lanny Poffo years before Muta came from Japan. In a standard moonsault, which is generally attempted from the top rope, a wrestler faces away from the prone opponent and executes a backflip landing on the opponent in a splash/press position but facing towards the elevated position. Though this move is generally attempted from the top rope to an opponent lying face up in the mat, myriad variations exist, including moonsaults that see the wrestler land on a standing opponent and forcing them down to the mat. The move is considered a higher-impact version of a splash, since the wrestler utilizes rotational speed.
A less common variation sees the wrestler perform a moonsault on a standing opponent, with the torso of the wrestler striking the torso of the opponent (albeit upside down), forcing the opponent backwards and to the ground with the opponent on top of them, usually placing the opponent in a pinning predicament. Most of the variations listed below can also be performed on standing opponents.
