"Hey Mr. DJ" is a song written by Van Morrison and recorded on his 2002 album, Down the Road.

It was released as a single in the United Kingdom and charted at number fifty-eight.

The Rolling Stone reviewer, David Fricke, said, "'Hey Mr. DJ' is a requiem for the one-on-one electricity of pre-Clear Channel radio, swinging with sweet brass and the iconic echo of Sam Cooke's 'Having a Party'.

"[1] The song was originally recorded in 2000 with Linda Gail Lewis, intended for an album entitled Choppin' Wood.

Before the release of the album, Lewis' contributions to the song were removed and string and vocal overdubs were added.
