Abkhazia–South Ossetia relations (Russian: Отношения Абхазии и Южной Осетии; Abkhaz: Аԥсны-Аахыҵ Уаԥстәыла азыҟаӡаара; Ossetian: Абхазийы-Хуссар Ирыстоны хъуыд) are bilateral foreign relations between the Republic of Abkhazia and the Republic of South Ossetia, whose international status is disputed – they are both considered part of Georgia by the majority of the world's states.

Abkhazia and South Ossetia recognized each other's independence by signing of treaty of friendship and cooperation or before.

[5][6] In recent years, the governments of Abkhazia and South Ossetia have been working closely together in search of more international recognition.

[7] During the 2008 South Ossetia war, Abkhazian soldiers and volunteers backed by Russian paratroopers drove Georgian troops from their last stronghold in Abkhazia's Kodori Valley while Russian and South Ossetian forces were engaged in heavy combat with Georgian forces.

[14] On 27 January 2014, President Ankvab recalled Nodar Pliev as ambassador to South Ossetia and appointed Alan Elbakiev as his successor.
