Appeal to the Great Spirit is a 1908 equestrian statue by Cyrus Dallin, located in front of the Museum of Fine Arts, Boston. It portrays a Native American on horseback facing skyward, his arms spread wide in a spiritual request to the Great Spirit. It was the last of Dallin's four prominent sculptures of Indigenous people known as The Epic of the Indian, which also include A Signal of Peace (1890), The Medicine Man (1899), and Protest of the Sioux (1904).
