Bol is a municipality located on the south side of the island of Brač within the Split-Dalmatia County of Croatia. It comprises the town of Bol and the village of Murvica, situated in a secluded position on the southern coast. As one of the oldest towns on Brač, it serves as a significant administrative center for this part of the Dalmatian region.

The name Bol is derived from the Latin word vallum, reflecting its historical roots. The town features historic buildings constructed by Venetian rulers and includes the Dominican monastery and the church of St. Mary of Mercy. This church was built and rebuilt throughout the 16th century, receiving its current Baroque form in 1641.

The area is defined by scenic landscapes and notable landmarks such as Zlatni Rat, a promontory composed of pebble rock that shifts with wind and waves. The town sits on a hill, making it walkable, while Vidova Gora offers views across the Dalmatian coast. The architecture includes ancient monasteries and houses from the Venetian era.

Bol is renowned for its tourism, particularly windsurfing conditions and the crystal-clear waters of Zlatni Rat. Visitors enjoy the Dominican Monastery museum, which holds artifacts and paintings by Tripo Kokolja, and the main altar work by Jacopo Tintoretto. The local culture also features Plavac Mali red wine produced by the Stina vinery.

The total population was 1,678 as of 2021, with 1,656 residents in Bol and 22 in Murvica. Access is primarily via ferry from Split or catamarans, with flights available to Brač Island during high season. The climate records show a high of 39.0 °C in 2017 and a low of −7.4 °C in the same year.
