Leverett Saltonstall (March 16, 1825–April 16, 1895) was an American political figure who served as Collector of Customs for the Port of Boston.
A member of the Saltonstall family, Saltonstall was born on March 16, 1825. His father, Leverett Saltonstall I, served as the first mayor of Salem, Massachusetts. Saltonstall graduated from Harvard College in 1844 and studied law at Harvard Law School and with the firm of Sohier & Welch. He was admitted to the bar in 1850.
Saltonstall began his political involvement with the Whigs, his father's political party. In 1854 he was appointed to the staff of Governor Emory Washburn.
By 1860, the Whig Party had dissolved and Saltonstall disapproved of the new Republican Party. He was a founder of the Constitutional Union Party. Saltonstall served as the party's state chairman and gave up his law practice to focus on the party. In 1860 he was the nominee of the Constitutional Union and Democratic parties for the United States House of Representatives seat in the Massachusetts's 3rd congressional district, but lost to Republican Charles Francis Adams Sr. After the Constitutional Union Party disappeared, Saltonstall became a Democrat. He was the Democratic nominee in the 7th congressional district in 1866, 1868, and the 1869 special election following George S. Boutwell's appointment as United States Secretary of the Treasury. Saltonstall was a War Democrat and made speeches encouraging enlistment in the Union Army. During the 1876 presidential election, Saltonstall spoke throughout the country for Samuel J. Tilden and served as an election monitor for the Democratic Party in Florida. He disputed the Republican victory there, charging them with manipulating the results.
