Ralph Izard (January 23, 1741/1742 – May 30, 1804) was an American politician who served as president pro tempore of the United States Senate in 1794.

He spent most of his childhood and youth studying in England: he attended a school in Hackney, London, and matriculated as a fellow-commoner at Trinity Hall, Cambridge.

In 1767, Izard married Alice De Lancey, who was a niece of James DeLancey and a descendant of Stephanus Van Cortlandt and Gertrude Schuyler.

After Izard moved to America in 1780 to focus on his work towards the American Revolution, his family stayed in France until 1783 when they joined him in South Carolina.

A cousin twice removed was Elizabeth {Eliza} Izard who was a daughter-in-law of Congressman of South Carolina Thomas Pinckney.
