"Y.M.C.A." is a song by American disco group Village People, written by Jacques Morali (also the record's producer) and singer Victor Willis and released in October 1978 by Casablanca Records as the only single from their third studio album, Cruisin' (1978). A medley with "Hot Cop" reached No. 2 on the US Billboard Dance Music Electronic Digital Song Sales chart.
The song remains popular and is played at many sporting events in the US and Europe, with crowds joining in on the dance by spelling out the four letters of the song's title via arm movements. "Y.M.C.A." is No. 7 on VH1's list of "The 100 Greatest Dance Songs of the 20th Century".
