USNS Harvey Milk (T-AO-206) is the second of the John Lewis-class of underway replenishment oilers, operated by the Military Sealift Command (MSC) to support ships of the United States Navy.

In July 2016, Ray Mabus, then United States Secretary of the Navy, advised Congress that he intended to name the John Lewis-class oilers after prominent civil rights leaders, with this ship to be named in honor of gay rights activist Harvey Milk.

[8] Milk served in the US Navy during the Korean War aboard USS Kittiwake (ASR-13), a submarine rescue ship, and held the rank of lieutenant (junior grade).

[9][10] Construction for both Harvey Milk, and USNS John Lewis (T-AO-205), the lead ship of the class, was authorized on 30 June 2016.

[2][15] On 11 July 2023, Harvey Milk entered non-commissioned U.S. Navy service under the control of the Military Sealift Command.
