Simon de Cramaud (c. 1345 – January 19, 1423, in Poitiers) was a Catholic bishop, titular Latin Patriarch of Alexandria, and cardinal during the Great Western Schism of the fourteenth and fifteenth centuries. His treatise De substraccione obediencie (1397), offering multiple lines of reasoning for bringing the Schism to an end, was edited by Howard Kaminsky in 1984. Simon argued that Benedict's followers could withdraw obedience to compel him to seek a solution to the Schism.
