Three ships of the United States Navy (and one ship of the Confederate States Navy) have been named USS Oregon, in honor of the 33rd state.

• The first Oregon was a brig purchased to support an exploratory expedition.
• A never-launched monitor previously named Quinsigamond and Hercules was also called Oregon before she was broken up in the ways.
• The second Oregon was a battleship that saw action in the Spanish-American War.
