Alexander Wolcott (September 15, 1758 – June 26, 1828) was a United States politician, customs inspector, and nominee to the Supreme Court of the United States. Nominated by James Madison in 1811, to replace the late William Cushing, Wolcott became only the second Supreme Court nominee to be rejected by the Senate in US history, by a vote of 9–24. The vote on his nomination constitutes the largest percentage of votes (72.73 percent) opposing any Supreme Court nominee in Senate history.
