Steve Nelson (born Stjepan Mesaroš; January 1, 1903 – December 11, 1993) was a Croatian-born American labor activist. He was one of nearly 3,000 American volunteers who joined the Abraham Lincoln Brigade in the Spanish Civil War, where he served as a political commissar. For years, he was a leading functionary of the Communist Party USA. He achieved public notoriety in the early 1950s when he was convicted and imprisoned under the Pennsylvania Sedition Act and the federal Smith Act. He is perhaps best remembered as the defendant in Pennsylvania v. Nelson, a U.S. Supreme Court ruling in 1956 which invalidated state sedition laws.
