USCGC Minnetonka (WHEC-67) was an Owasco class high endurance cutter built for World War II service with the United States Coast Guard.

Originally christened Sunapee, she was renamed after Lake Minnetonka, Minnesota, and commissioned as a patrol gunboat with ID number WPG-67 on 11 July 1946.

Her ID was later changed to WHEC-67 (HEC for "High Endurance Cutter" - the "W" signifies a Coast Guard vessel).

On the night of 29 February/1 March, she forced an enemy trawler, attempting to resupply the Viet Cong near Qui Nhon, to abandon its mission.

She fired a total 4,684 rounds of 5 in (130 mm)/38 ammunition, consisting of high-explosive, white phosphorus, and illumination projectiles during these missions.

The Minnetonka had 49 underway replenishments, receiving food, ammunition, mail, and personnel during her deployment to Southeast Asia.
