Sir John Walter (1566 – 17 November 1630) was an English judge and Member of Parliament.
He practised in the Exchequer and Chancery courts, becoming counsel to the University of Oxford, and in 1613 was appointed attorney general and trustee to the Prince of Wales.
He purchased the manor of Wolvercote from George Owen in 1616, and Cutteslowe from John Lenthall between 1611 and 1625.
[2] He married, firstly, Margaret Offley, daughter of William Offley, and they had these children:[3] After the death of his first wife he was remarried, in 1622, to Anne Witham, daughter of William Witham.
He settled Wolvercote on Anne and any children he might have with her (there were none), with remainder to David; she died childless in 1636.
