"No Mercy" is a song and single written by Hugh Cornwell, Dave Greenfield, Jet Black and Jean-Jacques Burnel performed by the Stranglers and released in November 1984.

One review of the album describes "No Mercy" as “a strong song, with often repeated simple guitar line”.

[4] The song was released on 1 December 1984 in 7-inch and 12-inch vinyl single formats as well as an ear sculpture shaped picture disc.

One version of the ending showed a dummy of Hugh Cornwell's body filled with tomato sauce hitting the floor in a bloody heap.
