Oregon men's basketball coach Dana Altman has retired after 16 seasons, the school announced Wednesday.
Altman, 68, is the winningest coach in Oregon program history, going 382-182 and reaching the NCAA tournament nine times, including the Final Four in 2017, during his tenure.
"I've loved every minute of coaching here, and stepping away is difficult and truly painful," Altman said in a statement. "I love coaching, it's what I know best and what I've been fortunate enough to do for almost five decades.
"... It's been the honor of my life to coach the Ducks."
Longtime assistant coach and former DePaul coach Tony Stubblefield will serve as the interim head coach for the upcoming season.
Altman, who also coached at Marshall, Kansas State and Creighton during his career, retires with a 792-425 record in his 37 seasons as a Division I coach, the 15th-most wins in NCAA history and fifth highest among active coaches.
"Dana built a program at Oregon to a level that very few coaches build anywhere," Oregon athletic director Rob Mullens said. "... The record book tells only part of the story. Dana and Reva have given so much of themselves to this university and to the young men who played for him, and we thank him for all his contributions to Oregon student-athletes, the game of basketball, and the University of Oregon."
The Ducks struggled to a 12-20 mark last season, including a 5-15 record in Big Ten play.
"I have had to make two really tough decisions in my coaching career," Altman said. "The first was leaving Creighton, a place my family and I dearly loved, to come to Oregon. This is the second.
"... I'm going to miss my coaches, my players and our incredible fans more than I can express. But I know this is the right thing to do at this time."
Oregon said it would begin a national search for a permanent head coach after this season.
Stubblefield was an original member of Altman's staff in 2010 and helped the Ducks earn eight NCAA berths. He was head coach at DePaul from 2021-24 before returning to Eugene in 2024.
"Tony has been on Dana's staff for most of his time in Eugene and knows this program as well as anyone," Mullens said. "Our student-athletes know him and trust him, and he is the right person to lead the Ducks this season."
