Żarki [ˈʐarki] (German: Zarki) is a town in Myszków County, Silesian Voivodeship, Poland, with 4,556 inhabitants (2019).

For centuries, Żarki belonged to Lelow County, Kraków Voivodeship, historic province of Lesser Poland.

It is not known when the village of Żarki received town charter: it happened before 1382, most likely during the reign of King Casimir III the Great.

During the month of October 1918, a short-lived local post was organized by the officer in charge of Civil Affairs of the District of Dabrow.

Later, in late 1941 or early 1942, Jews, including those who had been deported to Zarki, were forced into an overcrowded ghetto without much access to food and medical care.

The Polish farmers took the Jews to the train station in Zloty Potok and from there they were taken in freight cars to Treblinka where they were immediately murdered.
