Ardahan Province (Turkish: Ardahan ili) is a province in the north-east of Turkey, at the very end of the country, where Turkey borders with Georgia. The provincial capital is the city of Ardahan.

This is attractive open countryside which however spends many months of the year under snow. At this altitude temperatures on average reach -20°C and can drop below freezing all year round, including summer months.

The local economy depends on farming and raising livestock. Until 1993 Ardahan was a district of the province of Kars, becoming a province in its own right has meant more investment in infrastructure

There are two crossing points into the Samtskhe-Javakheti district of Georgia, one at Posof and the other (currently closed) at Çıldır. The Turkish military have a strong presence in this border district, another boost to the local economy.

Ardahan is an impoverished area that since the 1950s has seen a large number of its people migrate to other parts of Turkey or abroad. The population declined from 170,000 people in 1990 to 119,000 in 2000. The population is 105,454 as of 2010. Ethnic groups in the region include, Turkish people, Georgians, Kipchak^{[citation needed]}, Turkman^{[citation needed]}, Karapapaks^{[citation needed]} and Azeris^{[citation needed]}.
