Howell Edmunds Jackson (April 8, 1832 – August 8, 1895) was an American attorney, politician, and jurist.
He served as an Associate Justice of the Supreme Court of the United States, as a United States Senator from Tennessee and as a United States Circuit Judge of the United States Court of Appeals for the Sixth Circuit and the United States Circuit Courts for the Sixth Circuit.
Jackson was the first to bring a law school graduate with him to serve as his secretary-clerk on the Supreme Court; that secretary-clerk was James Clark McReynolds, who would later also became a Supreme Court Justice.
