Benjamin Guerard (1740 – December 21, 1788) was a lawyer, patriot of the Revolutionary War and the 34th Governor of South Carolina from 1783 to 1785.
Guerard was married on November 29, 1766 to Sarah Middleton, who died with their son on a sea voyage to New York City in 1775.
With the opening of the Southern theater in the American Revolutionary War, Guerard enlisted in the militia and participated in the siege of Charleston by the British in 1780.
Guerard was elected later in 1781 to the South Carolina Senate from St. Helena's Parish and was appointed a commissioner for the state to negotiate an agreement between the British and American forces to prevent plunder and maintain order from the evacuation of British troops from the state.
He returned as a member to the House of Representatives in 1783 for a brief period until his election by the General Assembly as Governor of South Carolina for a two-year term.
