Santiago Rodríguez Masagó (c. 1809 – 27 May 1879), also known as Santiago Rodríguez, nicknamed "Chago" was a Dominican military leader. Little is known of his birth but sources suggest that he was either born in Cap-Haïtien or the area of Fort-Liberté (in a part where it is present day Dajabón). He is known for having opposed the annexation of the Dominican Republic to Spain and then having fought the Spanish Crown; and for being one of the rebels of the famous "El Grito de Capotillo" that began the Dominican Restoration War with General Gregorio Luperón.
