Jesse Daniel Williams (born December 27, 1983) is an American high jumper and the 2011 World Champion.

Williams attended high school at Broughton High School in Raleigh, North Carolina, and attended North Carolina State University for one year (2003) before transferring and finishing his student-athlete career at the University of Southern California in Los Angeles where he won the NCAA track and field championships indoors 2005 and 2006 and outdoors in 2005 and 2006 becoming one of the few people to ever do so in the history of NCAA track and field.

During the 2009 indoor season he validated his off-season training at the elite Europa SC High Jump invitational, held at Banska Bystrica, Slovakia, on February 9, 2009.

At the 2010 IAAF World Indoor Championships in Doha, he claimed fifth place in the final (2.28m) while fellow American Dusty Jonas won the bronze.

Jumping for Team Nike/Oregon Track Club, Williams broke Hollis Conway's long-standing meet record at the Mt.

Kyriakos Ioannou (Cyprus) put the pressure on by clearing 2.33 on his third effort, but Williams responded immediately with his third try clearance, thereby retaining the lead on the count-back at 2.31: both then failed at 2.35.

Jumping in the green singlet of the Oregon Track Club Elite, he won the event with a Personal Best of 2.37 (7' 9 1/4"), which moved him to "equal third" on the all-time US outdoor list, behind only Charles Austin and Hollis Conway.
