"Substitute" is a song by Willie H. Wilson, recorded first by The Righteous Brothers and released as single from their album The Sons of Mrs. Righteous in 1975.

In 1978, the song became a big hit for the South African band Clout, reaching No. 2 in the UK charts in August and being certified Gold by the BPI. It fared even better in the rest of Europe where it reached No. 1 in Germany and Ireland, as well as No. 2 in Belgium, the Netherlands and Switzerland. This version was produced by Grahame Beggs.

A version by Australian group Peaches also charted locally at the same time, but was out-charted by the Clout track. It was also covered by Gloria Gaynor in 1978 and by Polish-Swedish singer and actor Izabella Scorupco in 1990.
