James A. Ryder SJ (October 8, 1800 – January 12, 1860) was an American Catholic priest and Jesuit who became the president of several Jesuit universities in the United States. Born in Ireland, he immigrated with his widowed mother to the United States as a child, to settle in Georgetown, in the District of Columbia. He enrolled at Georgetown College and then entered the Society of Jesus. Studying in Maryland and Rome, Ryder proved to be a talented student of theology and was made a professor. He returned to Georgetown College in 1829, where he was appointed to senior positions and founded the Philodemic Society, becoming its first president.
