"One Man Woman" is a 1980 song recorded by Scottish singer Sheena Easton.

The song was written by Mick Leeson and Peter Vale, and produced by Christopher Neil.

Following her launch on the TV show The Big Time, Pop Singer, Easton shot to success during the summer of 1980 with two top ten hits; "9 to 5" and "Modern Girl".

Like her previous two singles, this was again produced by Christopher Neil and recorded at AIR Studios in London.

The song was later included on her debut album, Take My Time, released early the following year.
