Matthew Arthur T. Southgate (born 3 October 1988) is an English professional golfer who plays on the European Tour.

His big breakthrough came in the 2016 Dubai Duty Free Irish Open where he finished fourth behind Rory McIlroy, earning him 200,000 euros.

Because he didn't replay the putt, he was handed a two-stroke penalty and another two strokes for signing an incorrect scorecard.

The cancer was diagnosed after he had played in the Aegean Airlines Challenge Tour in early July.

He returned to competitive golf in September, in time to compete in the first stage of the European Tour qualifying.
