"Dirty Deeds Done Dirt Cheap" is a song by Australian hard rock band AC/DC. It is the first track of their Australian album Dirty Deeds Done Dirt Cheap, released in September 1976, and was written by Angus Young, Malcolm Young, and Bon Scott. It is also the first track on the international version of Dirty Deeds Done Dirt Cheap, released in November 1976. The international version was not released in the United States until April 1981.

It was also released as a single, with "R.I.P. (Rock in Peace)" as the B-side in Australia, in 1976.

This is one of AC/DC's best known songs. It features a unique backing vocal consisting of a heavy breathing sound, made on the downbeat during verses. It is also the only AC/DC song to feature a line sung solely by Malcolm Young, who sings (in a spoken-word style) the title at the end of the chorus. The full length recording (approximately 4:11) has the title of the song chanted 4 times starting at 3:09, but on the more common edited version (approximately 3:51) the chant is heard only 2 times.
