Racha (also Račha, Georgian: რაჭა, Račʼa) is a highland area in western Georgia, located in the upper Rioni river valley and hemmed in by the Greater Caucasus mountains. Under Georgia’s current subdivision, Racha is included in the Racha-Lechkhumi and Kvemo Svaneti region (mkhare) as the municipalities of Oni and Ambrolauri.
Racha occupies 2,854 km2 in the north-eastern corner of western Georgia. Spurs of the Greater Caucasus crest separates Racha from the Georgian historical regions of Svaneti and Lechkhumi on the north-west and from Imereti on the south, while the main Caucasus ridge forms a boundary with Russia’s North Ossetia. On the east, Racha is bordered by breakaway South Ossetia, officially part of Georgia’s Shida Kartli region.
