Bălan (German: Kupferbergwerk; Hungarian: Balánbánya, pronounced [ˈbɒlaːmbaːɲɒ] ⓘ) is a town in Harghita County, Transylvania, Romania.

The town lies in the Ciuc Depression (Romanian Depresiunea Ciucului, Hungarian: Csíki-medence).

The copper deposits were discovered in 1785 by János Opra; production began in 1803, and by 1853 six mines were in operation.

Until 1967, Bălan remained part of the commune of Sândominic, finally gaining official town status in 1968.

Despite the environmental blight of the mining, the surrounding area is uncommonly beautiful, taking in the nearby mountains of Hășmașul Mare and Tarcău, the former a popular hiking destination.
