The Borač Castle (Serbian Cyrillic: Борач) was a noble court and one of the largest and most important fortified towns of medieval Bosnia, situated on top of rugged slopes high above the Prača river canyon, between Mesići and Brčigovo, near modern-day Rogatica, in Bosnia and Herzegovina. The fortified castle was a seat of the Pavlović noble family.

The family hailed and ruled from Borač. It is the first of two castles in their possession, which family used as a seat. Two castles were built in space of several decades and within few kilometers from each other, the second being Pavlovac, sometimes called New Borač or New Town.

The new castle or New Town or New Borač is actually called Pavlovac, and is considered to be a new structure, also known simply as Novi (English: New) or Novi Grad (English: New Town), situated on top of rugged slopes above the Prača river canyon, near modern days Prača village, in Bosnia and Herzegovina. Problem exist in correct dating of its construction, but some medieval charters suggest 1392, or late 14th century, as time of its construction, during Radislav Pavlović at the family's helm.

However, historians are certain that another Radinović-Pavlović fortress, original and older Borač than usually described Borač castle, existed, which was built around 1244 in the 13th century and located just a few kilometers downstream Prača river from New Town, near the location of present-day village Borač at 43°44′19″N 19°01′12″E / 43.738581°N 19.019926°E / 43.738581; 19.019926.
