Białobrzegi [bʲawɔˈbʐɛɡʲi] is a town in Masovian Voivodeship, Poland, about 65 kilometres (40 miles) south of Warsaw.

The town never gained significance and remained a small center, whose population was involved in trade and agriculture.

During the Polish January Uprising, several units operated in the area, and in 1870, as a Russian reprisal for residents’ support of the insurrection, Białobrzegi was stripped of its town privileges and became a settlement.

Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the settlement was occupied by Germany until 1945.

The town's main sports club is Pilica Białobrzegi [pl] with football, athletics and boxing sections.
