Oslnovice is a municipality and village in Znojmo District in the South Moravian Region of the Czech Republic.

The first written mention of Oslnovice is in a deed of King Ottokar I from 1228.

[2] After the Thirty Years' War, many Germans immigrated to Oslnovice and the village became ethnically mixed.

At the end of the 19th century, most of Germans moved away and the village became completely Czech again.

It is an Art Nouveau chapel decorated by Jano Köhler, which was moved to Oslnovice from Brno-Královo Pole in 1969.
