John Chandler Harper (March 10, 1914 – November 8, 2004) was an American professional golfer, best known for winning the PGA Championship in 1950. He won seven times on the PGA Tour and played in the Ryder Cup in 1955. Harper's competitive career lasted from 1938 to 1955; and like most professional golfers of his generation, he spent most of his time as a club professional. Harper compensated for his lack of driving distance with a strong short game; Ben Hogan said that Harper was the best putter on Tour.
