The Thaya (CzechDyje) is a river in Central Europe, tributary to the Morava. It is about 285 km long and meanders from west to east in the border area between Lower Austria (Austria) and Moravia (Czech Republic), but does not exactly follow the border in most parts. Its source is in two smaller rivers, namely the Deutsche Thaya (German Thaya) and the Mährische Thaya (Moravian 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.
