Úsov (German: Mährisch Aussee) is a town in Šumperk District in the Olomouc Region of the Czech Republic.

The highest point, located in the territory's exclave, is at 410 m (1,350 ft) above sea level.

In the 16th century, Úsov was in the possession of the lords of Boskovice, and in 1597 it was acquired by the House of Liechtenstein.

During the rule by Hans-Adam I of Liechtenstein, in 1692–1699, it was reconstructed and partially rebuilt into a large three-storey Baroque residence, designed by Domenico Martinelli.

However, in 1643, the developing community was affected by the invasion of Swedish troops, which caused many loss of life.

In the late 17th century, the community lived under the protection of Prince of Liechtenstein, and in the 1700s, the number of families reached 110.

The Jewish community disappeared during World War II as a result of the Holocaust.

The castle houses a museum, which was founded here by Johann II, Prince of Liechtenstein in 1898.

The Hunting and Forestry Museum contains a unique collection of trophies from Liechtenstein expeditions from around the world.
