USS Whitehall (1850) was a steamer acquired by the Union Navy during the American Civil War. She was assigned blockade duty; however, her condition was not always considered seaworthy, and she was plagued with condition problems. Whitehall—a side-wheel gunboat and converted ferry built in 1850 at Brooklyn, New York—was purchased by the Navy there on 10 October 1861 and was commissioned soon thereafter at the New York Navy Yard, Acting Master Francis P. Allen in command.
