Calamis (fl. 5th century BC) was a sculptor of ancient Greece.

He was possibly from Boeotia, but nothing certain is known of his life. He is known to have worked in marble, bronze, gold, and ivory, and was famed for statues of horses.

According to Pausanias (9.16.1), Calamis produced a statue of Zeus Ammon for Pindar, and at 9.22.1 mentions a Hermes Criophorus for Tanagra, which was later depicted on Roman coinage of the city. His status of Apollo Alexikakos stood in the Ceramicus of Athens. He produced his most ambitious work, a 30-cubit statue of Apollo for Apollonius Pontica (Pliny 34.29, Strabo 7.319). His Sosandra was praised by Lucian, and may have been copied for Aspasia, which in turn was copied by the Romans.

A different Calamis of the 4th century BC was a teacher of Praxias .
