Bliżyn [ˈbliʐɨn] ⓘ is a village in Skarżysko County, Świętokrzyskie Voivodeship, in south-central Poland.

[1] The village was first mentioned in 1410, when King Władysław II Jagiełło spent a night there on his way to the battle of Grunwald.

In 19th century Stanisław Staszic founded several minor manufactories and factories there, as part of his plan of creation of the "Old Polish Industrial Area".

During World War II the forests around Bliżyn were a mass murder site of Polish intelligentsia during the so-called AB Action.

There are also ruins of the 19th-century factories, a notable church and numerous remnants of dinosaurs in the rocky areas around the village.
