The Temple of Hercules Pompeianus (Latin: aedes Herculis Pompeiani) was a temple dedicated to Hercules in ancient Rome near the circus Maximus. Vitruvius (III.3.5) refers to it being decorated in the Tuscan manner. It contained a statue of Hercules by Myron.Pliny the Elder, Natural History, XXXIV.57 'Pompeianus' may indicate either that it was an older building built by the Pompeius family or that it was restored by Pompey the Great. It seems to be linked to Republican-era tufa foundations discovered under Santa Maria in Cosmedin.
