Alaverdoba (Georgian: ალავერდობა) is a religious and folk celebration in the eastern Georgian province of Kakheti, with its roots in a harvest festival. It focuses on Alaverdi Cathedral from which it derives its name, with the suffix –oba designating attribution. The festival lasts for several days, climaxing on 28 September, the feast day of St. Joseph of Alaverdi of the Thirteen Assyrian Fathers, the 6th-century founder of the cathedral.
