Waking Up in Vegas is a song by Katy Perry from her 2008 album One of the Boys, released as a single in 2009 and written about a spontaneous trip to Las Vegas. The chorus became the song's most quoted part, and short clips of it later circulated on soundboards and in short-form videos whenever creators wanted a quick Vegas reference. Its bright pop sound and instantly recognisable city name keep it useful for travel, party and gambling content, long after the original chart run.
