Samuel Salt (died 1792) was an English lawyer and Whig politician who sat in the House of Commons from 1768 to 1790.
On the interest of the Eliot family Salt was returned to parliament at the 1768 general election for their pocket-boroughs of St Germans and Liskeard.
Salt was expected to stand again at Liskeard in the 1784 general election but instead he stood for Aldeburgh in Suffolk on the interest of Philip Champion de Crespigny.
Charles was born in Crown Office Row, where Salt owned chambers, and it was the home of the Lamb family until 1792.
A shield with his coat-of-arms was placed in the sixteenth panel (counting from the west) on the north side of the Inner Temple hall.
