Czech Republic–Germany–Poland tripoint, International tripoint in Hrádek nad Nisou, Czech Republic.

The Czech Republic–Germany–Poland tripoint lies at 235 m above sea level on the Lužická Nisa river, where the Oldřichovský potok flows into it. The river forms the Czech–German and German–Polish state borders here, while the stream forms the Czech–Polish border, between Hrádek nad Nisou, Zittau and the village of Kopaczów.

The borders of these three nations were redrawn in 1945 following the Potsdam Agreement after World War II ended. This specific location became a tripoint where the three new boundaries came together following postwar territorial reorganization.

Three separate border markers and flags from each nation stand at this meeting point. They show how close the countries are to one another and mark the importance of this location in their shared border.

Walking paths connect to the tripoint from each of the three countries, with parking available near the Porajów-Zittau border crossing. The location is easy to reach on foot and offers good access for visitors exploring the area.
