Sir Walter St John, 3rd Baronet

Sir Walter St John, 3rd Baronet (May 1622 – 3 July 1708) was an English politician.

Biography He was the sixth son of Sir John St John, 1st Baronet of Lydiard Tregoze and inherited the baronetcy on the death of his nephew Sir John St John, 2nd Baronet (c. 1637–1657), the son and heir of Oliver, the son and heir apparent of Sir John, 1st Baronet.

In 1656, Sir Walter was Member of Parliament for Wiltshire (1656–1658 and 1659); for Wootton Bassett (1660–1679); and again for Wiltshire (1679–1681 and 1690–1695). He was famed for "piety and moral virtues".

In 1700, Sir Walter signed a trust deed that led to the formation of a school which later became the Sir Walter St John's School of Battersea.

Sir Walter died in his 87th year on 3 July 1708, and was buried on 9 July at Battersea. On his death the baronetcy passed to his son Henry St John who was created a viscount in 1716.
