Admiral John Schank (c. 1740 – 6 February 1823) was an officer of the British Royal Navy known for his skill in ship construction and mechanical design.

His talents as an engineer were applied in General John Burgoyne's expedition to the building of floating bridges.

After being made a captain in 1783, he brought before the Admiralty his design for ships with a sliding keel which allowed navigation of shallow waters.

His design was tested successfully and incorporated by the Admiralty into several larger vessels, most notably HMS Lady Nelson, which explored parts of Australia.

Mount Schank and Cape Schanck, Australia were named for the Admiral in December 1800 by Lieutenant (later Captain) James Grant during his exploratory mission of the region while commanding the Lady Nelson.
