Rychvald (Polish: Rychwałdⓘ, German: Reichwaldau) is a town in Karviná District in the Moravian-Silesian Region of the Czech Republic.

The village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from 1305 as Richinwalde.

[2][3] 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.

Bernard Barský of Bašť had built a Renaissance castle here in 1575–1577 and chose Rychvald as his family seat.

Following the Munich Agreement, in October 1938 together with the Trans-Olza region it was annexed by Poland, administratively organised in Frysztat County of Silesian Voivodeship.

The Starý Dvůr Castle is the oldest building in Rychvald, protected as a cultural monument since 1982.
