Reggie Theus (born October 13, 1957 in Inglewood, California) is a former NBA player and became the Kings 21st head coach on June 19, 2007.

Theus, who played 13 years in the NBA and was a member of the 1985 inaugural Sacramento Kings, is fresh off the heels of leading New Mexico State to a berth in the NCAA Tournament (a first for the school since 1999). Theus coached the Aggies for two seasons, compiling a 41-23 record. In his first year at the helm of the NMSU program, Theus guided the Aggies to a tie for the fifth-best turnaround in all of Division I basketball and the best single-season improvement of any NMSU squad since the 1985-86 season. He turned around a program that went 6-24 the year before he arrived (2004-05), leading the team to a 16-14 record, including wins over rival New Mexico and NCAA Tournament participants Pacific and Utah State. Theus' Aggies improved to 25-9 last season, winning the Western Athletic Conference Tournament.

Under Theus, NMSU also saw dramatic improvement in conference play as the Aggies went 10-6 in their first season as a member of the WAC. The nine-win improvement in conference play over the 2004-05 season was the Aggies? biggest single-season turnaround in school history. The Aggies swept three conference season series (Idaho, San Jose State, Utah State) while taking two of three meetings from Hawai?i and advancing to the conference championship semifinals.

Prior to his NMSU assignment, Theus spent two seasons as an assistant coach at the University of Louisville under head coach Rick Pitino. While at Louisville, he was an integral part of the Cardinals? run to the Final Four, the 2005 Conference USA regular season and tournament titles while helping lead the program to back-to-back 20-win seasons and a pair of NCAA Tournament appearances. In 2004-05, Theus helped guide Louisville back to the Final Four for the first time since their national title run in 1986.

Along with a successful career as both a player and coach, Theus has also been an influential member of the communities where he and his family have lived. Among the charitable programs which have benefited from Theus? involvement are the National Committee to Prevent Child Abuse, spokesperson for the NBA?s Stay in School Program, and Reggie Theus? Trikes for Kids.

Theus and his wife Elaine have three children; Raquel, Reggie and Rhyan
