Mary Ann Greene (June 14, 1857 – 1936) was a 19th-century American lawyer, writer, and lecturer from Rhode Island. She was the first American woman to be invited to address the World's Congress of Jurisprudence and Law Reform, where she delivered an address upon "Married Women's Property Acts in the United States, and Needed Reforms Therein."[1] She was also the first woman to publish in the American Law Review (1890), and the first woman to argue a case before the Rhode Island Supreme Court (1907).[2] Greene's principal literary works were articles on legal subjects, for magazines and papers, such as The Chautauquan and the American Law Review.[3]
