John Hahn (born February 6, 1989) is an American professional golfer currently competing on the European Tour.

Hahn won the 2009 Western Amateur.

Hahn qualified for the 2013 U.S. Open, in which he missed the cut.

Hahn earned his 2014 European Tour via qualifying school. After finishing 120th in the Race to Dubai, he had to re-qualify again in 2014. In the fourth round of a six-round qualifying school tournament, Hahn became one of four golfers in history to shoot a round of 58 in a professional tournament. Hahn's 58 came on the Tour Course at the PGA Catalunya Resort. The following day, Hahn shot a 78 at the nearby Stadium Course, taking him out of contention for the tournament. He finished the tournament in 50th place at 2-under-par. His best professional finish is third, which he achieved at the 2014 Africa Open.
