The Diu Indo-Portuguese creole (also Diu Portuguese Creole or Diu Portuguese) is spoken in Diu, India. It is a creole language based mainly on Portuguese and Gujarati. It is a member of the larger family of Indo-Portuguese creoles, particularly close to the variety of Daman. There is a considerably vital oral tradition in this language, with songs regularly performed in Diu, elsewhere in India and among Indo-Portuguese communities abroad.
Widely spoken in the past, it was first documented in the 19th-century by the initiative of Hugo Schuchardt. At present, the language is spoken natively by most of the local Catholics, numbering about 180, but is potentially endangered by the pressure of other languages such as Gujarati, English and standard Portuguese.
