John Austin (born 1613 at Walpole, Suffolk, England; died London, 1669) was an English lawyer and controversial writer.
He was a student of St. John's College, Cambridge, and of Lincoln's Inn, and about 1640 became a Catholic. He was well-regarded in his profession and was looked on as a master of English style.
His time was entirely devoted to books and literary pursuits. He enjoyed the friendship of such scholars as the antiquary Thomas Blount, Christopher Davenport (Franciscus a Santa Clara), John Sergeant, and others.
