John Sale (c. 1675 – 7 July 1732) was an Irish politician of the 18th century.
A "John Sale" was Sheriff of County Dublin in 1705; this may have been the same man.
[2] He was a Doctor of Laws and later registrar of the Church of Ireland diocese of Dublin.
[3] He was elected to the Irish House of Commons in 1715 for the Carysfort borough and served there until his death in 1732.
[4] His eldest daughter Elizabeth married Richard Wesley, 1st Baron Mornington and was the mother of Garret Wesley, 1st Earl of Mornington; thus, John Sale was great-grandfather to Arthur Wellesley, 1st Duke of Wellington.
