Rudná is a town in Prague-West District in the Central Bohemian Region of the Czech Republic. It has about 5,400 inhabitants.

After the municipality was established in 1951, it got its name derived from the Czech word ruda (i.e. 'ore'), which commemorates a long history of iron ore mining in the region. The name was invented by children at a local school, as many of their parents and grandparents worked in the local iron ore mines.

Rudná is located about 6 kilometres (4 mi) west of Prague. It lies in a flat agricultural landscape of the Prague Plateau. The highest point is at 410 m (1,350 ft) above sea level. The stream of Radotínský potok flows through the town.

Two villages, Hořelice and Dušníky, were originally located in the area of today's Rudná. The first written mention of Hořelice was in 1052. Dušníky was first mentioned in 1228, when both villages were property of St. George's Convent in Prague. While Hořelice was owned by various lower nobles from the 15th century, Dušníky was mainly church property and for the longest time it was owned by the Metropolitan Chapter at Saint Vitus in Prague.

In the 1860s, mining of iron ore began in the area. In 1936, both Dušníky and Hořelice were promoted to market towns. They continued to develop and they gradually created one urban unit. In 1951, Dušníky and Hořelice merged into a new municipality under the newly created name Rudná. Rudná was promoted to a town in 2000.
