The Subiaco Ephebe (or the Youth from Subiaco) is a sculpture of a young man approaching puberty found on the site of the Neronian Villa Sublaquensis at Subiaco (Roman Sublaqueum) in the upper Aniene valley, Lazio, Italy. The headless marble is a copy of a lost Greek bronze, as evidenced by an awkward tree-trunk support and "the failure of the total silhouette to keep manageably within the boundaries of a single block of stone", as Rhys Carpenter observes; it is unlikely to postdate Nero because of its find location. The date of the bronze original that it reflects is contested. When it was first found August Kalkmann gave it a date early in the fifth century BCE. but general opinion before World War II made it a work of the end of the fourth century in the turn towards Hellenistic style, to which Rhys Carpenter objected, suggesting instead that it belonged in the 60s or 70s of the fifth century.
