Campanula /kæmˈpæn.juːlə/ is one of several genera in the family Campanulaceae with the common name bellflower. It takes both its common and its scientific name from its bell-shaped flowers—campanula is Latin for "little bell".

The genus includes over 500 species and several subspecies, distributed across the temperate and subtropical regions of the Northern Hemisphere, with the highest diversity in the Mediterranean region east to the Caucasus. The range also extends into mountains in tropical regions of Asia and Africa.
