John Shaw was an Irish-born American officer in the United States Navy.

The USS Enterprise was a schooner, built by Henry Spencer at Baltimore, Maryland, in 1799. Her first commander thought that she was too lightly built and that her quarters, in particular, should be bulletproofed. Enterprise was overhauled and rebuilt several times, effectively changing from a twelve-gun schooner to a fourteen-gun topsail schooner and eventually to a brig. Enterprise saw action in the Caribbean, the Mediterranean, and the Caribbean again, capturing numerous prizes. She wrecked in July 1823.
