USS Passaconaway (YN-111/AN-86) was a Cohoes-class net laying ship built for the United States Navy during World War II.

Following shakedown, Passaconaway transited the Panama Canal and served with ServRon 4 during the later stages of World War II.

She tended anti-submarine nets in the Admiralty Islands during the summer of 1945, then for the next 12 months was engaged throughout the Western Pacific Ocean in other operations common to her type.

Following a brush with a typhoon in the spring of 1946, she was ordered to Pearl Harbor for repairs after which she returned to San Diego, California, where she decommissioned in December.

Passaconaway was transferred to the U.S. Maritime Administration in October 1962 as a part of the National Defense Reserve Fleet at Suisun Bay, California, until being transferred to MARAD National Defense Reserve Fleet, Suisun Bay, Benicia, California, in October 1970.
