LaSalle Thompson III (born June 23, 1961) is an American former professional basketball player, who spent most of his 15-year career with the Kansas City/Sacramento Kings and Indiana Pacers.

Nicknamed "Tank", Thompson finished his career at Texas as the school's all-time leader in rebounds with 1,027, despite the fact he played only three years.

During the 1984 NBA playoffs, Thompson averaged what would be postseason career-highs of 15 points and 10 rebounds per game, during a first round loss against the Los Angeles Lakers.

[2] A regular starter for most of the first part of his career, in 1992–1993 Thompson moved to a role as the tough-nosed veteran off the bench, as Rik Smits and Dale Davis started every game in which they played.

[4] Before the start of 2012–13 NBA season, Thompson became assistant coach of the New York Knicks under Mike Woodson (with whom he played for Kings in Kansas City and Sacramento) replacing Kenny Atkinson who quit joining the Atlanta Hawks staff.
