Arvaikheer, also spelt Arwaiheer (Mongolian: Арвайхээр, [arw̜æˑˈçeːr]; "Barley Steppe") is the capital of Övörkhangai Aimag (province) and one of the most central points of Mongolia.

It is a centre for traditional crafts, goat herding and equestrian sports, and hosts a large regional horse festival every year.

Its 1,813 metres (5,948 ft) elevation at the foot of the eastern hills of the Khangai Mountains augments its mildness by keeping it distant from cold-air pools in low basins.

Until 1990, Arvaikheer was the headquarters of a large division of the Soviet Army which had a profound influence on daily life in the town.

[5] After the fall of Soviet Communism, however, many public buildings were renovated or rebuilt, e.g. the Sports' Palace in the eastern part of the town.

The high street of Arvaikheer is a broad tree-lined avenue where two monuments dating from the times of the Mongolian People's Republic before 1990 are worth a visit as well.
