Francis Dade (1621 – May 1, 1662), also known as John Smith, was a Virginia politician and landowner. He was an English Royalist who emigrated to Virginia some time after the death of Charles I, possibly after involvement in some plot against Oliver Cromwell. He was notoriously attached to the Stuarts. In Virginia he adopted the name "John Smith". He served as Speaker of the Virginia House of Burgesses in 1658. He died at sea in 1662.
