Old Supetar was situated on the small peninsula where now stands a graveyard. The settlement came to an end during the early Christian era. In the late Middle Ages a new settlement arose around the bay known as St. Peter's (Sveti Petra), from which the town derives its name.
The present settlement of Supetar was founded in the 16th century when people living in Nerežišča, about 8 kilometres inland, began to use it as their harbour. The town's main period of development occurred during the 18th and 19th centuries when Supetar took over from Nerežišča as the administrative centre of the island of Brač.
