Sprint football, formerly called lightweight football, is a varsity sport played by United States colleges and universities, under rules similar to American football. The sport is currently governed by the Collegiate Sprint Football League.

Unlike conventional collegiate football which places a premium on body weight and strength, sprint football emphasizes speed and agility. Players must maintain a weight of 172 lbs or less and a minimum of 5% body fat to be eligible to play.

As of 2012, there are eight teams in the CSFL; of the eight, five are private universities (three being schools in the Ivy League) and two are national military academies; currently Mansfield University of Pennsylvania is the only state university or college playing sprint football. All eight teams are located in the northeastern United States. Three teams have been added since the 2008 season; none of the new additions have full-size varsity football teams. The other five teams (all of which have been in the CSFL since 1957) have full-size football teams that compete in NCAA Division I—the service academies in the top-tier FBS, and the Ivy League schools in the second-level FCS.. Each team plays a seven game season. In addition, Army, Cornell, Princeton, and Penn all hold alumni games in which sprint football alumni return to campus for a full-contact scrimmage against the varsity squad. The alumni games serve the dual purpose of raising funds to support the team and maintaining alumni interest in the program. Typically, the alumni have to donate a monetary weight penalty (e.g., $2 per pound) for weighing above the 172-pound limit.
