Kłokocin (German: Klokotschin) is a district of Rybnik, Silesian Voivodeship, southern Poland.

[1] The village was mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Clocochina decima more polonico.

[2][3] Politically it belonged initially to the Duchy of Racibórz, within feudally fragmentated Poland, ruled by a local branch of the Silesian Piast dynasty.

In 1327 the Upper Silesian duchies became a fee of the Kingdom of Bohemia, which after 1526 became part of the Habsburg monarchy.

After World War I in the Upper Silesia plebiscite 259 out of 281 voters in Kłokocin voted in favour of joining Poland, against 22 opting for staying in Germany.
