Peter Joseph Malnati (born June 13, 1987) is an American professional golfer who plays on the PGA Tour.

Malnati was born in New Castle, Indiana, and grew up in Dandridge, Tennessee,[3] where he attended Jefferson County High School.

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.

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.

The win earned Malnati an exemption on the PGA Tour through the end of the 2018 season.
