Strážný (until 1955 Kunžvart; German: Kuschwarda) is a market town in Prachatice District in the South Bohemian Region of the Czech Republic. It has about 400 inhabitants.

The villages of Hliniště, Kořenný and Řasnice are administrative parts of Strážný.

Strážný is located about 23 kilometres (14 mi) southwest of Prachatice and 55 km (34 mi) west of České Budějovice, on the border with Germany. It lies in the Bohemian Forest; most of the territory lies in the Šumava National Park and a smaller part lies in the Šumava Protected Landscape Area. The highest point is the Strážný mountain at 1,115 m (3,658 ft) above sea level, but there are also several other mountains above 1,000 m.

Two tributaries of the Vltava river, Řasnice and Častá, flow through the territory. The built-up area is located in the valley of the Častá, below the Strážný mountain.

The first written mention of Strážný, then named Kunžvart, is from 1359, when existence of a castle on the Strážný mountain is documented. For 200 years it served to protect an important trade route and border of the Kingdom of Bohemia. Since 1547, the castle was uninhabited, and during the 16th century, it became a ruin.

In 1689, a settlement was founded near the castle and named Kunžvart after the castle. The new village grew rapidly and already in 1833, the international road from Prague to Passau passed through here and one of the first bus lines in the country was in operation. In 1844, the village was promoted to a market town.

After World War II, the German population was expelled.
