The Thaya (Czech: Dyje [ˈdɪjɛ]) is a river in Central Europe, tributary to the Morava River. It is about 235 km long and meanders from west to east in the border area between Lower Austria (Austria) and South Moravia (Czech Republic), but does not exactly follow the border in most parts. Its source is in two smaller rivers, namely the German Thaya (Deutsche Thaya) and the Moravian Thaya (Czech: Moravská Dyje, German: Mährische Thaya), the confluence of which is located at Raabs. Its name means "the inert".

In its upper reaches, the Thaya flows through deep gorges, along which it passes many castles and chateaus. In Moravia, it has been dammed in several locations.

The name of the river bears also a small village Dyje in Znojmo District in the Czech Republic.
