Pervis Ellison (born April 3, 1967) is an American former National Basketball Association (NBA) player.

Teammate Danny Ainge gave Ellison the nickname "Out of Service Pervis" for the many injuries that would plague him during his professional career.

[2] Although he sometimes played as a backup in 1990–1991, the following year he became a full time starter and earned Most Improved Player honors after averaging 20.0 points, 11.4 rebounds and 2.68 blocks per game.

Among the best games of Ellison's NBA career occurred on January 31, 1992, when he recorded 19 points, 19 rebounds, 6 assists, 5 blocked shots and 2 steals against the Knicks.

Ellison signed with the Boston Celtics after he was released by Washington in April 1994, but did not play until midway through the following season because he was still rehabilitating from knee problems.
