Horní Planá (German: Oberplan) is a town in Český Krumlov District, in South Bohemia, Czech Republic.
The town is situated in the Bohemian Forest on the southeastern rim of the Šumava National Park, located on the northern shore of the Lipno Dam reservoir, south of the Boletice Military Training Area. Its picturesque setting, already perpetuated by the native poet Adalbert Stifter (1805–1868), makes it a popular destination for daytrippers. Beyond the Lipno reservoir, a densely forested area with several abandoned villages stretches up to the Vltava-Danube drainage divide (part of the main European Watershed) and the border with Austria at a distance of about 7 km (4 mi).
Horní Planá was part of the estates of Zlatá Koruna Abbey, founded by the Přemyslid king Ottokar II of Bohemia in 1263. It was vested with market rights by King Charles IV in 1349. Secularised during the Hussite Wars in 1420, it was incorporated into the Lordship of Český Krumlov, then held by the House of Rosenberg (Rožmberkové). The Rosenberg insignia were adopted in the town's coat of arms, awarded by Emperor Maximilian II in 1568.
The town received access to the United Bohemian Forest railway line from České Budějovice to the Černý Kříž railhub in 1892. In the early 20th century the local population predominantly consisted of Sudeten Germans. Oberplan was annexed by Nazi Germany upon the 1938 Munich Agreement and incorporated into the Reichsgau Oberdonau. After World War II it was restored to the Czechoslovak Republic, while the remaining German population was expelled.
