USS Herkimer (AK-188) was an Alamosa-class cargo ship that served the US Navy during the final months of World War II. Post-war she served in the Pacific Ocean theatre of operations for some time with the US Army as USAT Herkimer, and then as USNS Herkimer (T-AK-188), with the Military Sea Transportation Service (MSTS) from 1950 to 1973. She was then transferred to the navy of the Trust Territory of the Pacific Islands (TTPI).
