USCGC Iroquois (WHEC-43) was an Owasco class high-endurance cutter built for World War II service with the United States Coast Guard. The war ended before the ship was completed and consequently she never saw wartime service. Iroquois was built by Western Pipe & Steel at the company's San Pedro shipyard. Named after Lake Iroquois (Vermont), she was commissioned as a patrol gunboat with ID number WPG-43 on 9 February 1946. Her ID was later changed to WHEC-43 (HEC for "High Endurance Cutter" - the "W" signifies a Coast Guard vessel).
