Nathan Triplett (born March 15, 1987) is a former American football linebacker. After playing college football for Minnesota, he was drafted by the Minnesota Vikings in the fifth round of the 2010 NFL Draft. He has also been a member of the San Diego Chargers and Indianapolis Colts.

Triplett played in the Wright County Conference, graduating from Delano High School, in Delano, Minnesota, in 2005.

Triplett attended the University of Minnesota, where he initially was a special teams force and eventually worked his way into a dominant linebacker. In his senior season, in the first game of the year, he had possibly a game-saving interception, when vs Syracuse University in overtime he intercepted a pass in the Gophers own end zone to end the possession and give the Gophers the ball. The Gophers kicked a field goal on their possession to win the game. The next week vs United States Air Force Academy, with about 12 minutes left in the game, he recovered a fumble and returned it 52 yards for a touchdown, to break the 10-10 tie. The game ended at 20-13, so his touchdown was the game winner.
