Kurtis Eugene "Kurt" Warner (born June 22, 1971) is the starting quarterback for the Arizona Cardinals of the National Football League. He was originally signed by the Green Bay Packers as an undrafted free agent in 1994. He played college football at Northern Iowa.

Warner first reached fame for his highly successful stint with the St. Louis Rams from 1998-2003, where he won two NFL MVP awards in 1999 and 2001, as well as the Super Bowl MVP award in Super Bowl XXXIV. He also led the 2008 Arizona Cardinals to Super Bowl XLIII (the franchise's first-ever Super Bowl berth), and owns the three biggest single-game passing yardage totals in Super Bowl history. Warner is ranked among the top QB's all-time in career passer rating, behind Steve Young, and several active players, such as Peyton Manning, Tony Romo, and Phillip Rivers. Statistically, he is also the second-most accurate quarterback in NFL history (trailing only Chad Pennington), with a career completion percentage of 65.4%.. He also holds the highest completion percentage in a single game during regular season, at 92.3% (24/26), on 9/20/09, against the Jacksonville Jaguars.

Born in Burlington, Iowa, Warner played football at Regis High School in Cedar Rapids, Iowa, and went on to the University of Northern Iowa. At UNI, Warner was third on the Panthers' depth chart until his senior year. When Warner was finally given the chance to start, he was named the Gateway Conference's Offensive Player of the Year.
