John Ashwood (1657–1706) was an English Nonconformist minister and author in the 16th-17th century.
Soon after he was sent to London, where he was received into the family of the learned Theophilus Gale, who acted as his instructor.
Driven from Chard as a conscience-ruled Nonconformist by high-church intolerance, he decided with some friends to emigrate to Carolina in January 1683; but was prevented by a sudden attack of smallpox.
He then appears to have resided successively at Ilminster, Haveland, and Buckland, until he received a call to Exeter, where he was a minister for about ten years.
For about two years he was evening lecturer at Spitalfields, and morning preacher at Hoxton, when he received a call from a congregation at Peckham, Surrey.
