Thomas Barton (26 January 1757 – 1820) of Grove House and Clonmel, County Tipperary, and St Stephen's Green, Dublin, was an Irish landowner and politician.
He was born in 1757, the eldest son of William Barton of Fethard, County Tipperary, and his wife, Grace, daughter of Charles Massy, Dean of Limerick, and was educated at Trinity College, Dublin[1] and THe Middle Temple.
He also served as Recorder from 1801 to 1809, and represented the borough in the Irish House of Commons from 1783 to 1797.
When Fethard was disenfranchised at the Act of Union 1800, the compensation for loss of a pocket borough was divided between Barton and the family of Cornelius O'Callaghan, 1st Baron Lismore.
