John of Gothia (Greek: ᾿Ιωάννης ἐπίσκοπος τῆς Γοτθίας, Iōánnēs epískopos tēs Gotthiás[a]; died c. 791 AD) was a Crimean Gothic metropolitan bishop of Doros, and rebel leader who overthrew and briefly expelled the Khazars from Gothia in 787.

John of Gothia was born to a Crimean Gothic family, the son of Leon and Fotina, in Partenit, Crimea, where he grew up to become a bishop.

The Khazar garrison and Tudun were expelled from Doros, and the rebels seized the mountain passes leading into the country.

The Khazars however managed to retake the city in less than a year, and John was imprisoned in Phoulloi.

His remains were brought home to a church on the Ayu-Dag mountain, Partenit, Crimea, where a memorial to him has been built.
