Brac (pronounced "bräch"; Italian Brazza; Latin Bretia, Brattia) is an island in the Adriatic Sea within Croatia in central Dalmatia, with an area of 396 km2, making it the third largest island in the Adriatic, and thus the largest in Dalmatia. Its tallest peak, Vidova Gora stands at 778 m, making it the highest island point in the Adriatic. The island has a population of 13,000, living in numerous little villages and hamlets, ranging from the 'main town' Supetar, with more than 3,500 inhabitants, to Novo Selo, where only a dozen people live.

The economy of Brac is based mostly on tourism, but fishing and agriculture (especially wine and olives) are very important too, as is its precious white stone (which was used in building Diocletian's Palace in Split) and White House in Washington, D.C.. Historically, Brac was famous for goats; even Pliny comments that from the island of Brattia (the Latin name for the island) comes excellent cheese, wine and olive oil.
