Adam Matthew Vinatieri (born December 28, 1972 in Yankton (Yankton, South Dakota), South Dakota) is an American football placekicker currently playing for the Indianapolis Colts. He has played in five Super Bowls, four with the New England Patriots and one with the Colts, winning all but one. (The Colts went to Super Bowl XLIV but Vinatieri was a healthy scratch.) Vinatieri won a Super Bowl in 2006 with Indianapolis and won Super Bowls in 2001, 2003, & 2004 with the Patriots. Vinatieri is the first kicker ever to play in six Super Bowls and win four Super Bowl rings.

Vinatieri is generally considered to be one of the best clutch (clutch (sports)) kickers in the history of the National Football League. Nicknamed "Automatic Adam" for his accuracy, and "Iceman" for his incredible poise under pressure, Vinatieri has converted several of the most crucial field goals in NFL history, including game-winning kicks in the final seconds of two Super Bowls (XXXVI (Super Bowl XXXVI), XXXVIII (Super Bowl XXXVIII)).
