Tasov (German: Tassau) is a municipality and village in Žďár nad Sázavou District in the Vysočina Region of the Czech Republic. It has about 700 inhabitants.

Tasov is located about 32 kilometres (20 mi) south of Žďár nad Sázavou and 37 km (23 mi) west of Brno. It lies in the Křižanov Highlands. The highest point is at 530 m (1,740 ft) above sea level. The Oslava River forms the western border of the municipal territory. The village is situated in the valley of the Polomina stream, a tributary of the Oslava.

Tasov was most likely founded in the 12th century. The establishment of the settlement was connected with the nearby fortress. The first written mention of Tasov is from 1233, when the owner of Tasov became Záviš of Tasov. The village quickly developed and became a major religious centre serving parishes in nearby villages. In 1366, Tasov was first referred to as a market town.

In 1482, the Rohovský family bought a free farmstead here and becomes a prominent family in Tasov where they stayed until the mid-20th century, at which time they were forcibly evicted by the communist government. During the Thirty Years' War, Tasov was severely affected and about a third of the houses remained desolate. Between 1573 and 1644, Tasov was owned by Václav Berka of Dubá. In 1644, Tasov was inherited by the Fürstenberk family that greatly improved Tasov and neighbouring Budišov.

After World War II, Tasov was deprived of the title of market town.
