Goght'n (Armenian: Գողթն; also mentioned in sources as Goght'an, Գողթան, and spelled Gołt'n by modern scholars) was a canton (gavaṛ) located in the province of Vaspurakan in historical Armenia. Its borders roughly corresponded to the modern Ordubad Rayon of Nakhichevan, Azerbaijan.
Goght'n was well known for winemaking, the quality of its grape and fruit orchards. The region also was the birthplace of a number of prominent Armenian gusans (oral bards). The ancestors of the renowned twentieth-century Armenian composer and music ethnologist Komitas Vardapet were originally from Goght'n. Some of the region's oldest towns and villages have survived to this day, including Jugha (now Julfa) and Ordvat' (modern-day Ordubad).
According to Movses Khorenatsi, King Tigran Ervanduni (of the Orontid line) of Armenia, settled his wife and his daughters in an area to the east of (Ararat) and up to Goght'n, in Tambat, Oskiokh, Djaghguyn and other settlements giving them also three towns – Khram, Jugha and Khoshakunik, and on the other bank of the river (Arax) all the fields from Ajanakan up to the Nakhchavan Fortress. Mesrop Mashtots', the inventor of the Armenian alphabet, is assumed to have lived and worked in the town of Msrvanis (Mesropavan) during his stay in Goght'n. The Armenian princes of Goght'n probably had branched off from the family in Syunik' and had their own regional bishop. The second Gahnamak, or Military List, notes that the princes were expected during time of war to furnish 500 cavalry to help defend the Kingdom of Armenia's southern gate (that is, its southern border).
