Isaac Pusey Gray (October 18, 1828 – February 14, 1895) was the 18th and 20th governor of the U.S. state of Indiana from 1880 to 1881 and from 1885 to 1889. Originally a Republican, he oversaw the forceful passage of the post-American Civil War constitutional amendments while he was a member of the Indiana Senate. He became a Democrat following the corruption of the Administration of Ulysses S. Grant but was regularly stymied by his Democratic adversaries who constantly referred to his tactics while a Republican, earning him the nickname "Sisyphus of the Wabash."
