Kellen Moore (born July 5, 1988) is a former American football quarterback who is the quarterbacks coach of the Dallas Cowboys of the National Football League (NFL). He played six seasons in the NFL for the Cowboys and Detroit Lions. He played college football at Boise State. Moore holds the unofficial all-time record for wins by a starting quarterback in NCAA Division I FBS with a 50–3 (.943) record. As a junior, he finished fourth in the balloting for the 2010 Heisman Trophy.
Moore was born and raised in Prosser, Washington. His father, Tom, was head coach at Prosser High School from 1986 to 2008, winning 21 league titles and four state championships. During football season, he and younger brother Kirby, who also played at Boise State as a wide receiver, practiced plays in the backyard after football practice. As his father remembered in a 2011 interview, "He'd always have a little notepad with him. He was always drawing plays." In his final two years of high school, his father let him call his own plays.
