Bagavan (also spelled Bagawan; Armenian: Բագաւան) was an ancient locality in the central part of Armenia in the principality of Bagrevand.

[1] Situated on a tributary of the Euphrates at the foothills of Mount Npat, to the north of Lake Van, Bagavan held one of the major temples of pre-Christian Armenia.

[1][2] The royal family of Armenia celebrated the New Year's festival at Bagavan, on the first day of the first month (Nawasard) of the Armenian calendar.

[1] According to Agathangelos, Tiridates III of Armenia (r. 287–330) and his court were baptized by Gregory the Illuminator at Bagavan in the Euphrates.

[1] Hewsen notes that it was originally surrounded by a "high wall flanked with towers which protected the monasting buildings within".
