Teschen district, Administrative district in Austrian Silesia, Austria

Teschen District was a political district of Austrian Silesia that existed from 1850 to 1855 and again from 1868 to 1920, with its seat in the city of Teschen. After the Friedek legal district was separated on 1 October 1901, it covered 730 km² and comprised 70 municipalities in the Teschen and Jablunkau legal districts.

Created in 1850 after the 1848 reforms, the district was abolished in 1855, restored in 1868 with Friedek added, and lost Friedek on 1 October 1901. It then covered 730 km² and 70 municipalities. After World War I the Spa Conference divided it on 28 July 1920 between Czechoslovakia and Poland.

The district's population was traditionally divided between Cieszyn Vlachs in the north and Silesian Gorals in the south, speaking Cieszyn Silesian and Jablunkov dialects. In the 1910 census, 55.5% of residents were Roman Catholic, 41.7% Protestant and 2.6% Jewish. Census results on national identity were disputed and fuelled political quarrels in the region.

The historic district no longer exists as an administrative unit and is now divided between Poland and the Czech Republic. Those interested in exploring its past can find information in local museums and archives in the towns that once served as its centers.

The district's 1910 population was 55.5% Roman Catholic, 41.7% Protestant and 2.6% Jewish, and included about 5,500 immigrants from Galicia and 4,300 from Bohemia and Moravia. The censuses of 1880–1910, which recorded language and religion, were themselves a subject of political dispute over national identity.
