The Mesmes language is an extinct West Gurage language, one of the Ethiopian Semitic languages spoken in Ethiopia. There are still many people who claim the Mesmes ethnic identity, but none who speak the language. The last speaker of the language was interviewed by a language survey team when he was approximately 80 years old. He had not spoken the language for 30 years, having nobody to speak it with when his brother had died.
