Radvanice (Polish: Radwanice, German: Radwanitz) is a part of the city of Ostrava, Moravian-Silesian Region in the Czech Republic.
The settlement was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Radwanowitz.
The creation of the village was a part of a larger settlement campaign taking place in the late 13th century on the territory of what will be later known as Upper Silesia.
Politically the village belonged initially to the Duchy of Teschen, formed in 1290 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.
It witnessed heavy industrialization at the end of the 19th century, locals worked mainly in coal mines.
