Arriach is a municipality in the district of Villach-Land in the Austrian state of Carinthia.
Situated within the Nock Mountains range of the Gurktal Alps, about 20km (10miles) north of the city of Villach, Arriach houses the geographical centre of the state of Carinthia. The commune is a state-recognised health resort, its economy mainly depends on tourism.
The municipal area consists of the four cadastral communities: Arriach proper, Innerteuchen, Laastadt, and Sauerwald.

The parish of Ovriach was first mentioned in a 1207 deed. In early modern times, the remote area was a centre of Crypto-protestantism in the Duchy of Carinthia. The present-day municipality was established in 1850; the Sauerwald community joined in 1898.
According to a 2001 census 68.8% of the population were Protestants, which is the highest percentage of all Carinthian municipalities. Therefore, the Four Evangelists parish church, a Neo-Gothic building erected in 1903, is the largest Protestant church in mainly Catholic Carinthia. It is located at the site of a former 'prayer house' (Bethaus), built after the Patent of Toleration was issued by the Habsburg emperor Joseph II in 1781. Furthermore, Arriach's coat of arms depicts a Eucharist chalice and a Luther rose.
The smaller Catholic parish church dedicated to Sts. Philipp and Jakob, erected about 1200 and rebuilt several times, stands nearby. Arriach also features several historic rustic log homes preserved in quite good condition.
