Vulcan (de|Wolkendorf; hu|Szászvolkány) is a commune in Brașov County, Transylvania, Romania, 16 km west of the county capital Brașov. It is composed of two villages, Colonia 1 Mai (Konkordiabányatelep) and Vulcan. It also included Holbav village until 2004, when it was split off to form a separate commune.
Since its founding around the year 1377, it was one of the most important villages in the Burzenland area, where there was a strong Transylvanian Saxon community.
