Sir John Hayward (c. 1591 – April 1636) was an English politician and landowner.
He was MP for Bridgnorth in 1621 and for Saltash in 1626, as well as High Sheriff of Kent in 1623 and of Montgomeryshire in 1632.
Originally from an old Shropshire family, his father was a wealthy merchant and twice Lord Mayor of London.
[1] In 1615, Hayward inherited his elder brother George's estates in Acton Burnell; around 1624, he moved to Hollingbourne in Kent and married his recently widowed cousin Anne, mother of Sir Michael Livesey, a regicide who approved the Execution of Charles I in January 1649.
They had no children and when he died in 1636, he was buried next to his father in St Alphege London Wall.
