In the past, Supetar was located on the small peninsula where now stands a graveyard. During the early Christian era the settlement came to an end. 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.
In the 16th century was founded the present settlement of Supetar when people living in Nerežišča, about 8 kilometres inland, began to use it as harbour. The main period of development of the town occurred during the 18th and 19th centuries. In this period, Supetar took over from Nerežišča as the administrative centre of the island of Brač.
