Southern California extended the contract of coach Andy Enfield for two years, the school announced.
The extension runs through the 2020-21 season. No contract terms were disclosed.
Enfield originally signed a six-year deal in 2013 that was worth more than $1 annually when USC lured him away from Florida Gulf Coast.
"We are very excited about the direction of our men's basketball program under Coach Enfield and the progress that has been made," USC athletic director Pat Haden said in a statement. "We look forward to continued progress, and we believe that with this contract extension, Coach Enfield will bring stability and success to USC men's basketball for the long term."
The Trojans went 21-13 this past season and reached the NCAA Tournament in Enfield's third season. USC lost to Providence in the opening round of the NCAA tourney.
The Trojans cracked the Associated Press Top 25 poll during the regular season for the first time since 2008.
"We look forward to an off-season of continued development for our players that will set the foundation for an exciting 2016-17 season," Enfield said in the statement.
