Glenn Anton Rivers (born October 13 1961 in Chicago, Illinois), commonly referred to as Doc Rivers, is a retired American basketball player and is currently the head coach of the NBA's Boston Celtics. Rivers was known for his defense while playing in the NBA. His skills as floor general and point guard helped him transition into a coach following his playing career.

After representing the United States with the national team in the 1982 FIBA World Championship, in which he was selected as the tournament MVP, and graduating from the Marquette University, Rivers was drafted in the second round of the 1983 NBA Draft, moving into the starting lineup due to injury during his rookie season. He spent the next seven seasons as a starter in Atlanta, assisting star Dominique Wilkins as the team found great regular season success. He averaged a double-double for the 1986-87 season, scoring 12.4 points and helping out with 10.0 assists. Rivers later spent one year as a starter for the Los Angeles Clippers and two more for the New York Knicks, before finishing out his career as a solid bench player.

Rivers began his coaching career with the Orlando Magic, where he coached for more than four NBA seasons. Rivers won the Coach of the Year award in 2000 after his first year with the Magic. That season, he led the team that was picked to finish last in the league to a near playoff berth. He made the post season in his next four years as coach, but was fired in 2003 after a disastrous start to the season. Rivers took over the Boston coaching position in 2004 after spending a year working at the American Broadcasting Company as a commentator for The NBA on ABC.

On January 21, 2008, Rivers earned the honor to coach the Eastern Conference All-Stars for the 2008 NBA All-Star Game in New Orleans as a result of the Celtics' 109-93 victory over the New York Knicks.

He is married to Kristen Rivers and has three children. His oldest son Jeremiah plays for Georgetown University.
