Árva County (Hungarian: Árva vármegye, Latin: Comitatus Arvensis, Slovak: Oravská stolica/župa,[1] German: Komitat Arwa, Polish: Komitat Orawa) was an administrative county (comitatus) of the Kingdom of Hungary since the 14th century until 1920.

The county's territory was situated along the Árva (Orava) river between Zázriva (Zázrivá) and the Tatra mountains.

After the destruction of the town by the Lithuanian troops in 1683, the seat was moved to Alsókubin (also Kolbin, Kublen, Kubin, Also Helben, Clbin, Culbyn, Cublyn, present-day Dolný Kubín).

[2] Emerging from the Zólyom royal land (Hungarian: zólyomi erdőispánság), the first written mention about Árva County is from 1349.

In the aftermath of World War I, the territory of the whole county became part of newly formed Czechoslovakia.
