Three ships of the United States Navy have been named USS Montana in honor of the 41st state.

• The first Montana (ACR-13), a Tennessee-class armored cruiser, provided convoy escort duty during World War I, and was eventually renamed and reclassified Missoula (CA-13).

• The second Montana (BB-51), a South Dakota-class battleship, was laid down but cancelled and scrapped before launching.

• The third Montana (BB-67) would have been the lead ship of her class of battleship had the class not been cancelled.

The movies The Abyss and The Fifth Missile both feature a fictional Ohio-class submarine named "USS Montana", but no submarine has ever borne that name.
