The 2000 United States Senate election in Rhode Island was held on November 7, 2000. Republican U.S. Senator John Chafee had announced in 1999 that he would not seek reelection, leading his son, Lincoln Chafee, to announce his own candidacy. The elder Chafee, however, died a few months later; his son was appointed to fill the remainder of the unexpired term. The younger Chafee, now the incumbent, sought a full term and won, defeating Democratic U.S. Representative Bob Weygand. As of 2022, this is the last congressional election in Rhode Island to be won by a Republican.
