Vroutek (German: Rudig) is a town in Louny District in the Ústí nad Labem Region of the Czech Republic. It has about 1,900 inhabitants.

The villages of Lužec, Mlýnce, Mukoděly, Skytaly, Vesce, Vidhostice and Vrbička are administrative parts of Vroutek.

Vroutek is located about 35 kilometres (22 mi) southwest of Louny and 48 km (30 mi) north of Plzeň. The eastern part of the municipal territory with the town proper lies in the Rakovník Uplands. The western part lies in the Doupov Mountains and includes the highest point of Vroutek, the hill Skytalský vrch at 552 m (1,811 ft) above sea level. The Blšanka River flows through the southern part of the territory.

The first written mention of Vroutek is from 1227, when the village was owned by Kojata IV Hrabišic. In the 14th century, it was acquired by the monastery in Postoloprty and sometime during that time it was promoted to a town. Before the Thirty Years' War, it was owned by various noble families, including the Lobkowicz family. Most of the town was destroyed by the fire in 1599. The Czernin family acquired Vroutek in 1630 and annexed it to the Petrohrad estate.

In 1645, during the Thirty Years' War, Vroutek was looted and destroyed by the Swedish army. For more than 10 years, most of the houses remained abandoned. Then the town was resettled by ethnic Germans.
