John Preston, 1st Baron Tara (4 November 1764 - 18 July 1821), was an Irish politician.
Preston was the son of John Preston,[1] a descendant of a younger brother of Thomas Preston, 1st Viscount Tara, second son of Christopher Preston, 4th Viscount Gormanston.[2] He inherited Bellinter House.
He was elected to the Irish House of Commons as one of two representatives for Navan in 1783 (aged only 18), a seat he held until the Irish Parliament was abolished in 1800.[3] He was raised to the Peerage of Ireland the same year as Baron Tara, of Bellinter in the County of Meath, a reward for his support for the Union.[2]
Lord Tara was childless and the title became extinct on his death in July 1821, aged 56.
