Thomas Henry Barclay (October 12, 1753 – April 21, 1830) was an American lawyer who became one of the United Empire Loyalists in Nova Scotia and served in the colony's government.

After attending King's College (later Columbia University), he studied law with John Jay and was called to the bar in 1775.

In 1785, he was elected to the 6th General Assembly of Nova Scotia representing Annapolis County while Edmund Fanning was governor. The next year, John Parr became governor. In 1793, Barclay was elected for Annapolis Township and served as speaker for the assembly. He also served as lieutenant-colonel in the colony's militia and was boundary commissioner for the British when the border between the United States and New Brunswick was settled in Jay's Treaty. Although he was appointed to the Council for Nova Scotia in 1799, he was given the post of British consul general in New York City later that year succeeding Sir John Temple. Barclay was recalled to London for the duration of the War of 1812.
