Bolków [ˈbɔlkuf] (German: Bolkenhain) is a town in Jawor County, Lower Silesian Voivodeship, in south-western Poland. It is the seat of the administrative district (gmina) called Gmina Bolków and part of the Neisse-Nysa-Nisa Euroregion.

The town lies at the Nysa Szalona River, approximately 15 kilometres (9 mi) south-west of Jawor, and 70 kilometres (43 mi) west of the regional capital Wrocław. As at 30 June 2010, it has a population of about 5,301.

First mentioned as Hain in a 1276 deed, Bolków was named after Duke Bolko II of Świdnica, who died in 1368. His duchy was incorporated into the Lands of the Bohemian Crown of the Holy Roman Empire. Since 1945 the town belongs to Poland.

Above the town stand the ruins of Bolków Castle, built in the 13th century. Devastated in the Thirty Years' War it became a property of Grüssau Abbey in 1703, though restoration efforts did not begin until 1905. Since 1994 the ruin is the site of the annual "Castle Party" Gothic rock festival.
