Daniel Lloyd Monson (born October 6, 1961) is an American college basketball coach who is currently the head coach at Eastern Washington. He was previously the head coach at Long Beach State for 17 seasons. He was also the head coach at Minnesota for over seven seasons, reaching postseason play five times. Before coaching the Gophers, he was the head coach at Gonzaga for two seasons, leading the team on an improbable run to the Elite Eight during his last season.

Monson is the son of college basketball coach Don Monson, and spent most of his early years in eastern Washington, where his father was a successful high school head coach in Cheney and Pasco for 18 seasons. At age 14, the family moved from Pasco to East Lansing, Michigan, where Don was an assistant coach for Jud Heathcote at Michigan State for two seasons.

They moved to Moscow, Idaho, at the start of his junior year, when his father became the head coach of his alma mater, the University of Idaho, in August 1978. He graduated from Moscow High School in 1980 and played college football a few blocks away as a receiver for the Idaho Vandals, then under head coach Jerry Davitch. Monson suffered a knee injury that ended his playing career, and focused on coaching; he graduated from Idaho with a degree in secondary education (mathematics) in 1985.

After graduation, Monson was a high school coach (and math teacher) in Oregon City for a season, then became a collegiate graduate assistant under Gene Bartow at UAB in 1986, where he earned a master's degree in education.

Monson began at GU as an assistant coach in 1988 and was elevated to associate head coach under head coach Dan Fitzgerald in 1994; in all, Monson spent eleven years helping build the Gonzaga program. As an assistant, Monson was a key figure in the Bulldogs turnaround during the 1990s. Gonzaga had a record of 223–89 (.715) over ten seasons and he was responsible for recruiting many of the key players in Gonzaga's NCAA Sweet 16 appearances from 1998–2001. From the time Monson was named associate head coach in 1995, Gonzaga averaged 22 wins per season and reached postseason play every year but one. For all of this, Monson was promoted to head coach of the Zags in 1997.

His first year as head coach at Gonzaga (1997–98) resulted in a 24–10 mark, as the Bulldogs won the West Coast Conference championship and advanced to the second round of the NIT. On their way to setting a school-record with its 24 wins, Monson was named the WCC Coach of the Year and National Rookie Coach of the Year by Basketball Times.

The 1999 team brought Gonzaga basketball to national prominence with an impressive run in the NCAA tournament. In the West regional, the tenth-seeded Zags defeated 7th-seed Minnesota and second-seed #7 Stanford in the Seattle sub-regional, then sixth-seed Florida in the Sweet Sixteen round in Phoenix. Gonzaga advanced to the regional final (Elite Eight), taking the region's top seed, eventual national champion Connecticut, down to the last minute, losing by five points.

While at the helm at Gonzaga, Monson had a 52–17 (.754) record in his two seasons and won both regular season titles.
