Koszęcin [kɔˈʂɛnt͡ɕin] is a village in Lubliniec County, Silesian Voivodeship, in southern Poland. It is the seat of the gmina (administrative district) called Gmina Koszęcin. It lies approximately 13 kilometres (8 mi) south-east of Lubliniec and 43 km (27 mi) north of the regional capital Katowice.

The village was first mentioned in 1277, when it was part of fragmented Piast-ruled Poland. Later on it passed to Bohemia (Czechia). In 1640, Koszęcin was bought by Fryderyk Blacha. It was annexed by Prussia in the 18th century, and from 1871 it was also part of Germany. It was the site of fights during the Polish Third Silesian Uprising against Germany in 1921, and afterwards it was reintegrated with Poland, which just regained independence following World War I.

It was occupied by Germany following the joint German-Soviet invasion of Poland, which started World War II in September 1939. The occupiers operated the E416 forced labour subcamp of the Stalag VIII-B/344 prisoner-of-war camp in the village. After Germany's defeat in the war, in 1945, the village was restored to Poland.

It was previously in Częstochowa Voivodeship (1975–1998).
