Lelów [ˈlɛluf] (Yiddish: לעלוב - Lelov) is a village in Częstochowa County, Silesian Voivodeship, in southern Poland.

In the early days of the Kingdom of Poland, a gord was established on the Białka river bank, in a swampy area, which gave protection from invaders.[when?]

The town was occupied by German and Czech troops, loyal to Bishop Jan Muskata (see also Rebellion of wójt Albert).

Its population reached 1,200, and King Casimir III the Great built here a castle, and surrounded the town with a defensive wall.

Lelów was located near the border with Czech-ruled Silesia, and as such, played an important role in the system of defence of Poland.
