Velký Šenov (German: Groß Schönau) is a town in Děčín District in the Ústí nad Labem Region of the Czech Republic.

The Sebnitz River (here called Vilémovský potok) originates in the woods in the southeastern part of the municipal territory and flows through the town proper.

In 1827, a button factory started operating, but at the end of the 19th century the production moved to Lipová.

[3] From 1938 to 1945, Velký Šenov was annexed by Nazi Germany and administered as a part of the Reichsgau Sudetenland.

The original medieval church was replaced by the current Renaissance building in the second half of the 16th century, and was modified in the 1780s.
