Bělá nad Radbuzou got its name probably from the Radbuza River, which was called here Bílý potok ('white stream').

Bělá nad Radbuzou is located about 9 kilometres (6 mi) north of Domažlice and 37 km (23 mi) southwest of Plzeň. The town is situated at the confluence of the Radbuza River and the stream Bezděkovský potok. The built-up area lies in the Upper Palatine Forest Foothills, but most of the municipal territory lies in the Upper Palatine Forest and borders Germany in the west.

The first written mention of Bělá nad Radbuzou is from 1121, when the near Přimda Castle was built. Until 1600, Bělá nad Radbuzou was a part of the Přimda estate. In the 16th century, it became a property of Lamminger of Albenreuth, a Bavarian noble family. In 1614 the Lamminger family built a small Renaissance castle and a brewery. After the Battle of White Mountain, in 1623, the estate was merged with Újezd Svatého Kříže and the castle ceased to serve as the seat of the estate. In 2014, the castle burned down.
