William J. Laimbeer Jr. (born May 19, 1957) is an American professional basketball coach and former player.

In his National Basketball Association (NBA) career, Laimbeer was known for his 11-year tenure with the Detroit Pistons during their "Bad Boys" era.

Prior to the NBA, he played for the University of Notre Dame and Palos Verdes High School in Southern California.

After his playing career, Laimbeer served as the head coach and general manager of the Detroit Shock in the WNBA from 2002 to 2009, coaching the team to three league championships in 2003, 2006, and 2008. He was the head coach of the New York Liberty from 2013 to 2017 and the head coach of the Las Vegas Aces from 2018 until 2021. He has twice been named the WNBA's Coach of the Year.
