Sangley and Mestizo de Sangley are archaic terms used in the Philippines during the Spanish colonial era to describe respectively a person of pure overseas Chinese ancestry and a person of mixed Chinese and native Filipino ancestry. The Sangley Chinese were ancestors to both modern Chinese Filipinos and modern Filipino mestizo descendants of the Mestizos de Sangley, also known as Chinese mestizos, which are mixed descendants of Sangley Chinese and native Filipinos. Chinese mestizos were mestizos in the Spanish Empire, classified together with other Filipino mestizos.
