Calenzana is a commune in the Haute-Corse department of France on the island of Corsica. In 1732 it was the site of an uprising by Corsican nationalists against the island's Genoese rulers. It is now best known as the starting point of the GR 20 long distance walk. The commune contains the Étang de Crovani, a coastal lagoon, that lies behind the Crovani beach on Crovani bay.
