"Dub Be Good to Me" is a 1990 single by British dub group Beats International, released on 29 January 1990. It was a #1 hit in the United Kingdom, and hit #1 on the Billboard Hot Dance Club Play in the United States. It is generally considered the band's signature song.

"Dub Be Good to Me" was written by Beats International frontman Norman Cook. It samples the songs "Guns of Brixton" by The Clash and the Once Upon a Time in the West theme by Ennio Morricone, and includes interpolations of the songs "Just Be Good to Me" by The SOS Band and "Jam Hot" by Johnny Dynell.

Written by Norman Cook (aka Fatboy Slim), "Dub Be Good to Me" was the sole number one single for Cook's genre-hopping outfit Beats International.

The track started out as an instrumental with the title "The Invasion of the Estate Agents". While also included as the B-side to this single, it originally appeared as the B-side to Cook's 1989 single "For Spacious Lies". This instrumental track is heavily based on the bassline from The Clash's "Guns of Brixton" with a sample of the distinctive "harmonica" theme from the epic western film Once Upon a Time in the West, written by Ennio Morricone. This instrumental, in slightly remixed form, had vocals added from The SOS Band's "Just Be Good to Me" (as re-recorded by Lindy Layton) to form "Dub Be Good to Me".
