"Word of Mouth" is a song by English rock group Mike + The Mechanics, released in March 1991 by Atlantic and Virgin as the lead single from their third album, Word of Mouth (1991).

The music video was directed by Paul Boyd and premiered in early 1991.

The song is driven by electric guitar and synthesizer hooks played in unison, as well as the powerful vocal performance of Paul Young, who sings multiple B4 chest voice high notes.

Coupled with layered hand clap and audience effects, the song has a distinctive live, stadium rock sound.

AllMusic lauded the track as a "rousing singalong" and "killer pop song.
