The Mount McKinley-class command ship was a ship class of command ships of the United States Navy during World War II and the Cold War. All eight ships were converted from Type C2-S-AJ1 cargo ships.

Eight type C2 cargo ships were converted into command ships for the US Navy throughout the middle to later stages of World War II. After the war, all were modernized with new radars and all decommissioned by the 1970s to be later scrapped.

The ship's hull remained nearly the same but with new equipment to carry out her purpose now placed on deck alongside several cranes. The ships' armaments had been slightly changed and relocated in order for the ships to carry out their new roles. All ships served in the Pacific Theater until the end of the war with no ships lost in combat.
