The 1972 United States Senate special election in Vermont took place on January 7, 1972. Incumbent Republican Robert Stafford, appointed in September 1971 to fill the vacancy created by the death of Winston L. Prouty, successfully ran for election to the remainder of Prouty's term in the United States Senate. Stafford defeated Democratic candidate Randolph T. Major. Liberty Union candidate Bernie Sanders received 2% of the vote and was later elected to this seat in 2006 as an independent.
