USS McNulty (DE-581) was a Rudderow-class destroyer escort in the United States Navy during World War II.

After shakedown off Bermuda, McNulty trained along the east coast until leaving Chesapeake Bay on escort duty with UGS‑46 to Bizerte, Tunisia.

Her guns helped drive off an attacking German bomber 12 July 1944, and her convoy safely reached Bizerte 2 days later.

McNulty patrolled off Luzon 29 January as the San Narciso Attack Force carried out the landings which spearheaded the drive to take Manila.

She arrived San Diego 5 November, decommissioned there 2 July 1946, and entered the Pacific Reserve Fleet, where she remained at least into 1969.
