Jonathan Paul "J. P." Losman (born March 12, 1981 in Venice, California) is an American football quarterback for UFL Las Vegas of the United Football League. He was drafted by the Buffalo Bills 22nd overall in the 2004 NFL Draft. He played college football at Tulane.

After a notable high school career at Venice High School where he earned Parade All-American honors and was rated the No. 3 quarterback in the nation by PrepStar Magazine, Losman accepted an athletic scholarship to attend college at UCLA. He enrolled early during the spring semester of 1999, in order to compete for the starting quarterback position. However, due in part to distractions from friends and family who attended Bruins practices, Losman opted to demand that he be the starting quarterback for the upcoming season. However, UCLA suggested to him that he would not be the starter, forcing Losman to find a NCAA Division I program in which he could compete for the job as starting quarterback.

Losman eventually transfered to Tulane University to play for then-head coach Chris Scelfo, who had made a late recruiting run at him just prior to his committing to UCLA. While Tulane had long been an academic powerhouse, its football program had for the most part struggled in recent years – with the notable exception of a 12-0 season in 1998 in which the program won the Liberty Bowl and finished ranked 7th in the nation.
