John Anthony Nicholson (November 17, 1827 – November 4, 1906) was an American lawyer and politician from Dover, in Kent County, Delaware. He was a member of the Democratic Party, and served as U.S. Representative from Delaware.
Nicholson began his career as briefly the superintendent of the free schools of Kent County in 1851. At the same time he studied law with Martin W. Bates in Dover, was admitted to the Delaware Bar in 1850, and began a law practice in Dover. In addition he served as brigadier general of militia in Kent County in 1861. In 1864 he defeated the Republican and Ultimate Unionist candidate Nathaniel B. Smithers, another Dickinson graduate, and was ultimately elected as a Democrat to the 39th and 40th Congress, serving from March 4, 1865, to March 3, 1869. During the first term he was on the Committee of Elections and in the second the Appropriations Committee. He was not a candidate for renomination in 1868 and continued his practice of the law.
