Avery Point Light or Avery Point Lighthouse is a lighthouse in Groton, Connecticut, United States, on the Avery Point Campus of the University of Connecticut. Although construction was completed in March 1943, the lighthouse was not lit until May 1944 due to concerns of possible enemy invasion. Its original light consisted of eight 200-watt bulbs that were later replaced by a flashing green light in 1960. It was deactivated on June 25, 1967, when the United States Coast Guard Training Station moved to Governors Island. It is officially listed as the last lighthouse built in the state; the only other claimant is the replica Mystic Seaport Light.
