Thomas Dalton (died 1730) was an English judge who became Chief Baron of the Irish Exchequer.
Dalton was born in Hampshire, eldest son of the Reverend Peter Dalton; his mother is said to have belonged to a Dublin family called Dominick. He graduated from Queen's College, Oxford in 1702 and became a fellow of All Souls' College in 1706. He was called to the Bar in 1711. In 1725 he was appointed Lord Chief Baron of the Irish Exchequer and held office until his death in 1730, aged about fifty-five. He was buried in St. Andrews' Church, Dublin.
According to Elrington Ball, during his academic career he had a reputation for pride and arrogance; but he earned a good reputation as Chief Baron and after his premature death tributes were paid in verse to him as a " learned and unbiased judge."[1]
