Stoczek Łukowski [ˈstɔt͡ʂɛk wuˈkɔfskʲi] is a town in Łuków County, in Lublin Voivodeship, in eastern Poland with 2,556 inhabitants (as of January 2018[update]).

Stoczek Łukowski belongs to the historic province of Mazovia, in which it was part of the Land of Czersk.

After the Polish victory in the Austro-Polish War of 1809, it was included within the short-lived Duchy of Warsaw.

Stoczek was one of main centers of the January Uprising, for which in 1867 it was stripped of town charter, and remained a village until 1916.

Following the German-Soviet invasion of Poland, which started World War II in September 1939, the town was occupied by Germany until 1944.
