Peter Malnati (born June 13, 1987) is an American professional golfer who has played on both the PGA Tour and Web.com Tour.
Malnati played on mini-tours until earning special temporary membership on the Web.com Tour (equivalent to 100th on the previous season's money list) in 2013. He won his seventh tournament of the 2013 season at the News Sentinel Open. He finished 18th on the 2013 Web.com Tour regular-season money list to earn his 2014 PGA Tour card.
In November 2015, Malnati earned his maiden PGA Tour victory by winning the Sanderson Farms Championship by one stroke over William McGirt and David Toms after a Monday finish to the tournament. He shot a five-under round of 67 to come from one behind to take the victory over a crowded leaderboard. The win earned Malnati an exemption on the PGA Tour through the end of the 2018 season.
