Intelligent Whale is an experimental hand-cranked submarine developed for potential use by the United States Navy in the 1860s.

Intelligent Whale was built on the design of Scovel Sturgis Merriam in 1863 by Augustus Price and Cornelius Scranton Bushnell.

In 1864 the American Submarine Company was formed, taking over the interests of Bushnell and Price and there followed years of litigation over the ownership of the craft.

They submerged the boat in 16 feet (5 m) of water and Sweeney, clad in a diver's suit, emerged through a hole in the bottom, placed a charge under a scow, and reentered the submarine.

Following the failed trial in 1872, Intelligent Whale was put on display at the Brooklyn Navy Yard and remained there until 1968 when she was moved to the Washington Navy Yard where she remained until being relocated to the National Guard Militia Museum of New Jersey in Sea Girt, New Jersey, where she is currently on display.
