Samuel Hanna (1772?–1852), Irish presbyterian divine, was born at Kellswater, near Ballymena, Co. Antrim.
A warm advocate of Sunday schools and of bible distribution, he was also one of the first to interest Irish presbyterians in the subject of missionary enterprise.
Hanna, in June 1817, was unanimously elected professor of divinity and church history, with an emolument of £36.00 a year (he retained his congregation).
In 1840 Hanna was freed from active pastoral work by the election of William Gibson, D.D., as his assistant and successor at Rosemary Street.
Love to Christ: An Incitement to Ministerial and Missionary Exertions (1822) Sympathy of Irish Presbyterians with the Church of Scotland (1840) Hanna died at the residence of his son-in-law, Dr. Denham, at Derry, on 23 April 1852, in his eighty-first year.
