Calcagno is a surname derived from the Latin calx, calcis ("heel"), through the later forms calcaneum and calcanium, both meaning "heel" or the back part of the foot. According to the authors cited, the surname originated as a nickname given to an individual because of a physical characteristic, peculiarity, or perhaps an injury associated with that part of the body.

Like many medieval descriptive surnames, the nickname eventually became hereditary and was passed down through successive generations.
