The Ara Maxima Herculis, or Great Altar of Hercules, was an ancient open-air altar and cult site in Rome located in the Forum Boarium area near the Tiber River. It served as one of the principal cult sites dedicated to Hercules in the city.

The area offers views of late Republican and Imperial period urban fabric and ancient riverfront sanctuaries.
