The Umm Leisun inscription (Georgian: უმ ლეისუნის წარწერა, romanized: um leisunis ts'arts'era) is an Old Georgian limestone tombstone slab.

It has a five-line[1] inscription written in the Georgian Asomtavruli script and was discovered in 2002, after the renewal of 1996[2] excavation at a Georgian monastery of the Byzantine period, in the neighborhood of Umm Leisun, in the southern part of Sur Baher, 4.5 km southeast of the Old City of Jerusalem.

[6] Per sex estimation for human skeletons, all of them were adult males, as would be expected in a monastery.

[9] The inscription is the earliest known example for an ethnonym ႵႠႰႧႥႤႪႨ (kartveli i.e. Georgian) on any archaeological artifact, both in the Holy Land and in Georgia.

[10][11] The inscription covers an area of 81 × 49 cm cut into the tombstone.
