Alaverdi Monastery (Georgian: ალავერდის მონასტერი, romanized: alaverdis monast'eri) is a Georgian Eastern Orthodox monastery located 25 km (16 mi) from Akhmeta, in the Kakheti region of Eastern Georgia.

While parts of the monastery date back to 6th century, the present day Cathedral of Saint George was built in the 11th century by Kvirike III of Kakheti, replacing an older church of St. George.

It is considered one of the four Great Cathedrals of the Georgian Orthodox world.

[1] The monastery was founded by the Assyrian monk Joseph (Yoseb, Amba) Alaverdeli, who came from Antioch and settled in Alaverdi, then a small village and former pagan religious center dedicated to the Moon.

The monastery is the focus of the annual religious celebration Alaverdoba.
