The Autocephalous Turkish Orthodox Patriarchate (Turkish: Bağımsız Türk Ortodoks Patrikhanesi), also referred to as the Turkish Orthodox Church (Turkish: Türk Ortodoks Kilisesi), is an unrecognized autocephalous Eastern Orthodox organization based in Turkey. It was founded in Kayseri by Pavlos Karahisarithis, who became the patriarch and took the name of Papa Eftim I, in 1922. The church is headquartered in Istanbul.

The Patriarchate is unrecognized by other Orthodox Churches and is considered non-canonical. It is seen as a "family business", as "Papa Eftim's church had a very small congregation, and after his death in 1968 it consisted of his family members only". The Patriarchate only makes political declarations in the Turkish press and does not engage in expected church functions like liturgy, religious thought, or spiritual life.
