The 1947 Notre Dame Fighting Irish football team represented the University of Notre Dame during the 1947 college football season. The Irish, coached by Frank Leahy, ended the season with 9 wins and no losses, winning the national championship. The 1947 team became the sixth Irish team to win the national title and the second in a row for Leahy. The squad is the second team in what is considered to be the Notre Dame Football dynasty, a stretch of games in which Notre Dame went 36-0-2 and won three national championships and two Heisman Trophies from 1946-1949. The 1947 team was cited by Sports Illustrated as the part of the second best sports dynasty (professional or collegiate) of the 20th century and second greatest college football dynasty.
