William West was an American militia general in the American Revolutionary War, Justice of the Rhode Island Supreme Court, Deputy Governor of Rhode Island, and anti-federalist leader. West also was a party in the first U.S. Supreme Court decision in 1791, West v. Barnes.

The Rhode Island Supreme Court is the court of last resort in the U.S. State of Rhode Island. The Court consists of a Chief Justice and four Associate Justices, all selected by the Governor of Rhode Island from candidates vetted by the Judicial Nominating Commission. Each justice enjoys lifetime tenure and no mandatory retirement age, similar to Federal judges. Justices may be removed only if impeached for improper conduct by a vote of the Rhode Island House of Representatives and convicted by trial in the Rhode Island Senate.
