Denis Durnian (born 30 June 1950) is an English professional golfer.

He never won a European Tour event, but he finished second four occasions, with one being a defeat in a matchplay final, and twice losing out in a playoff.

The tournament became a European Tour event the following season, and he was twice the British Club Professional Champion.

Durnian played in The Open Championship every year from 1982 to 1990, only making the 36-hole cut on one occasion, in 1983 at Royal Birkdale, when he went on to finish tied for 8th place.

During the second round he set the record for the lowest nine-hole total in the Open, with 28 on the front nine.
