Harvey Unga (born January 18, 1987) is an American football running back who is currently a free agent. He was drafted by the Bears with a seventh round pick in the 2010 Supplemental Draft. He played college football at Brigham Young where he became the school's all-time leading rusher.
After the season-opener against the Arizona Wildcats in 2007, Unga earned the Mountain West Conference (MWC) offensive player of the week award. He had gained 194 all-purpose yards, with 127 yards coming from receptions. Unga became the starting running back in 2007 due to an injury to Fui Vakapuna in the prior season. As a starter, Harvey rushed for over 1000 yards in just 11 games, with this mark reached in the second quarter against their in-state rivals, Utah, on November 24, 2007. He was named the MWC Freshman of the Year. He had the second-most yards gained by a freshman in MWC history, and third among all freshman running backs in the nation in 2007.
In 2009, Unga rushed for 1,087 yards and 11 touchdowns, and became the school's all-time leading rusher with 3,455 yards. He earned first-team All-MWC honors following the season.
On April 16, 2010, Unga voluntarily withdrew from BYU after violating its honor code.
