Trans-Olza (, ; , Záolší; ), also known as Trans-Olza Silesia (), is a territory in the Czech Republic which was disputed between Poland and Czechoslovakia during the Interwar Period. Its name comes from the Olza River.

The history of the Trans-Olza region began in 1918 when, after the collapse of Austria-Hungary, the newly-established Czechoslovakia claimed the area, which was mainly inhabited by Poles. Poland maintained control over the region and began to hold elections, to which Czechoslovakia responded by invading and annexing the territory in January 1919.
