"Party Out of Bounds" is a song by American new wave band the B-52's, from their second album, Wild Planet (1980). Featured with the other dancefloor-bound tracks from the album, the song peaked at number five on the US Billboard Hot Dance Club Play chart in 1980 as an album cut and has long been a staple of alternative/new wave dance club playlists.^[1] Lyrically, the song is a guide on how to better plan house parties in order to prevent potential disasters. An instrumental dub mix was included on the B-side of the vinyl 45 rpm single "Private Idaho".

The following year, another mix of "Party Out of Bounds" appeared on the B-52's' Party Mix! EP, remixed by Daniel Coulombe and Steven Stanley to feature elements of the dub mix, embellished with echoes and additional keyboard effects. Two years later, Stanley produced and engineered the B-52's' 1983 album Whammy!.

The song begins with the B-52's crashing a party, with the opening beat punctuated by a discordant guitar riff implying unexpected arrival, Fred Schneider screaming "Sur-PRI-ise!" and Kate Pierson belting out "PAR-TAY!". It quickly becomes evident that this party is poorly planned and executed. The balance of the lyrics describe what can go wrong at a party, how to remedy these bad situations, and prevent them from happening in the first place with proper planning.
