Kirk Alan Triplett (born March 29, 1962) is an American professional golfer who has played on the PGA Tour, Nationwide Tour, and Champions Tour.

Triplett was born in Moses Lake, Washington, and grew up in Pullman. He graduated from Pullman High School in 1980 and accepted a golf scholarship to the University of Nevada in Reno, where he earned a degree in civil engineering. He became a golf professional in 1985.

He won three tournaments on the PGA Tour: the Nissan Open in 2000, the Reno-Tahoe Open in 2003, and the Chrysler Classic of Tucson in 2006. He also finished second at the 1992 Houston Open, 1995 Buick Invitational, 2000 John Deere Classic, 2001 Michelob Championship at Kingsmill and 2003 Bay Hill Invitational.

Triplett was a member of the U.S. team in the 2000 Presidents Cup, where he claimed three wins and a halved match. He has been featured in the top 50 of the Official World Golf Ranking.

In 2009 he finished outside the top 150 on the money list and lost his PGA Tour playing card. In the 2011 Nationwide Tour, he won the News Sentinel Open at age 49 to become that tour's oldest winner ever.

The player became eligible to play on the Champions Tour in 2012, after March 29. Triplett won his first tournament in his eighth attempt on July 9, 2012 when he won the Nature Valley First Tee Open at Pebble Beach. He entered the final round four strokes behind but shot a final round 66 to surge through the pack and prevail by two strokes over Mark McNulty. The win made him the sixth player to win on all the PGA Tour sponsored tours (PGA Tour, Web.com Tour, and Champions Tour). He successfully defended the title in 2013, picking up his second Champions Tour win.

Triplett shot a tournament record 9-under-par at the Principal Charity Classic at West Glen Oaks Country Club in Des Moines, Iowa.
