Marc Elton Cayeux (born 22 February 1978) is a Zimbabwean professional golfer.

He was born in Lancaster, England and raised in Zimbabwe, leaving school at 14 to pursue a career in golf.

That win gained him entry to the WGC-NEC Invitational, where he played with World Number 1 and eventual winner Tiger Woods in the first round.

A less successful season in 2006 saw Cayeux return to the Sunshine Tour the following year, where he had four top three finishes on his way to eighth in the Order of Merit.

In 2008, he won the Nashua Masters, and regained his place on the European Tour through the qualifying school.
