Old Supetar was situated on the small peninsula where there is now a graveyard. The settlement came to an end during the early Christian era. In the late Middle Ages a new settlement started around the bay known as St. Peter's, from which the town derives its name. It originated from the Latin S.v Petar during the Latin population of the town. "Sv" stands for "Sveti", meaning saint, therefore it takes its name from Saint Peter, which is the name's English equivalent translation.
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.
