Didnauri (Georgian: დიდნაური) is a Late Bronze Age/Early Iron Age archaeological site in Georgia, located in the steppes of the Shiraki Plain in the country's southeasternmost municipality of Dedoplistsqaro.

The National Agency for Cultural Heritage Preservation of Georgia, which supports the ongoing field works, has described it as "the largest ever ancient settlement" unearthed in the South Caucasus.

Preliminary digs revealed ruins of a large settlement, which was dated by a team of Georgian archaeologists to the period of 12th to 9th century BC.

The settlement is encompassed by a 1.5 km-long and 7 m-wide defensive wall made of clay and wooden logs, "unique in its scale and design", as described by the expedition led by the archaeologist Konstantine Pitskhelauri.
