Henry Hamilton (March 28, 1788 – June 1, 1846) was an American lawyer and politician from New York.

In 1806, he removed from Herkimer County, New York to Schoharie, New York, and taught school. He studied law, and was admitted to the bar. In 1816, he married Maria Lawyer (1800–1867).

He was District Attorney of Schoharie County from 1818 to 1821. He was Surrogate of Schoharie County from 1832 to 1840.

In 1840, he was elected by the New York State Legislature one of the canal commissioners, and remained in office until 1842 when the new Democratic majority removed the Whig commissioners.

He was buried at the Old Stone Fort Cemetery in Schoharie.
