Sackville Hamilton PC (Ire) (14 March 1732 – 29 January 1818) was an Anglo-Irish politician.
Hamilton was born on 14 March 1732. He was the third son, of seven children born to Mary Dawson (daughter of Joshua Dawson) and Hon. Henry Hamilton, MP and Collector of the Port of Cork. His younger brother was Henry Hamilton, who served as royal Governor of Bermuda and Dominica.
Hamilton entered the Irish House of Commons for St Johnstown (County Longford) in 1780 and sat for the constituency until 1783. Subsequently he was elected for Rathcormack and Clogher. He chose the latter and was a Member of Parliament for the constituency until 1795, resigning the seat to be Escheator of Munster, a notional ‘office of profit under the crown’. In the following year he stood successfully for Armagh Borough, which he represented until 1798.
In 1780, Hamilton was appointed Under-Secretary to the Lord Lieutenant of Ireland. He held this post until February 1795 and again from May of the same year until 1796. In 1796, he was sworn of the Privy Council of Ireland
