Portugis, or Ternateño, was a Portuguese-based creole language spoken by Christians of mixed Portuguese and Malay ancestry in the islands of Ambon and Ternate in the Moluccas (Indonesia), from the 16th to the middle of the 20th century.
Ternateño may have contributed to or evolved into Ternate Chabacano. Around 1660 the Spanish evacuated the garrison in Ternate to Manila, and with them a group of local Christians, probably speaking Ternateño, called mardikas arrived in the Philippines.
