The Meghri (Armenian: Մեղրի, pronounced [mɛɣˈɾi], also known as the Meghriget) is a tributary of the Aras River in the Syunik Province of southern Armenia.

It descends steeply through the province, stretching 36 kilometres (22 mi) in length from its headwaters at Blue Lake to its confluence with the Aras, as a left tributary, south of the town of Meghri.

[4] Due to its geographical separation from the rest of Armenia, several species of plants that grow within the Meghri basin are not found elsewhere in the country.

Endangered in Armenia, otter populations have seen some recovery in the basin, where they frequently steal fish and pose a nuisance to aquaculture.

[6] However, lower water levels from the installation of hydroelectric stations has caused many to migrate to the Aras itself.
