Varagavank (Armenian: Վարագավանք, 'Monastery of Varag'; Turkish: Yedi Kilise, 'Seven Churches') was an Armenian monastery on the slopes of Mount Erek (Varag), 9 km (5.6 mi) southeast of the city of Van, in eastern Turkey.

The monastery was founded in the early 11th century by Senekerim-Hovhannes Artsruni, the Armenian King of Vaspurakan, on a preexisting religious site. Initially serving as the necropolis of the Artsruni kings, it eventually became the seat of the archbishop of the Armenian Church in Van. The monastery has been described as one of the great monastic centers of the Armenian church by Ara Sarafian and the richest and most celebrated monastery of the Lake Van area by Robert H. Hewsen.

During the Armenian genocide, in April–May 1915, the Turkish army attacked, burned, and destroyed much of the monastery. More of it was destroyed in the 1960s, although some sections are still extant.

Before Christianity, the site had a significant religious importance during the Urartian period as attested by the presence of inscriptions dedicated to gods Ḫaldi and Teišeba and later housed a sanctuary of Vahagn, the Zoroastrian Verethragna, whose name may have been the source of the name Varag.

According to tradition, in the late third century, the Roman virgin Hripsime, fleeing the Diocletianic Persecution, hid the remnant of the True Cross she wore on her neck at the site of the monastery. In 653, when the location was discovered, Catholicos Nerses III the Builder built the Church of Surb Nshan (Holy Sign), described by Robert H. Hewsen as "a simple hermitage". Nerses also established the Feast of the Holy Cross of Varag (Varaga surb khachi ton), celebrated by the Armenian Apostolic Church on the Sunday nearest to 28 September, always two weeks after the Feast of the Cross.

Queen Khushush, the daughter of King Gagik I of Armenia and spouse of Senekerim-Hovhannes Artsruni, the future Artsruni King of Vaspurakan, built a church at the site in 981 dedicated to the Holy Wisdom (Surb Sopi). In the late medieval period, it was converted into a castle and was known as Berdavor (berd meaning 'fortress' in Armenian). The Church of Surb Hovhannes (Saint John) was built to the north in the 10th century.

The monastery itself was founded by Senekerim-Hovhannes early in his reign (1003–24) to house a relic of the True Cross that had been kept on the site since Hripsime. In 1021, when Vaspurakan was annexed by the Byzantine Empire, Senekerim-Hovhannes took the relic to Sebastia, where the following year his son Atom founded the Surb Nshan Monastery. In 1025, following his death, Senekerim-Hovhannes was buried at Varagavank and the True Cross was returned to the monastery. Fearing an attack by Muslims, Father Ghukas of Varagavank took the True Cross in 1237 to the Tavush region of northeastern Armenia. There he settled in the Anapat monastery, which was renamed Nor Varagavank. In 1318, the Mongols invaded the region and ransacked the monastery. All the churches were destroyed except St. Hovhannes, which had an iron door and was where the monks hid. Between 1320 and the 1350s, the monastery was completely restored.

The Safavid emperor Tahmasp I ransacked the monastery in 1534. In 1648, along with other buildings in the region, Varagavank was destroyed by an earthquake. Its restoration was begun immediately thereafter by monastery father Kirakos who found financial support among the wealthy merchants in Van. According to the 17th-century historian Arakel of Tabriz, four churches were restored and renovated.
