The Oppian Hill is the southern spur of the Esquiline Hill, one of the Seven Hills of Rome, Italy. It is separated from the Cispius on the north by the valley of the Suburra, and from the Caelian Hill on the south by the valley of the Colosseum. The Oppius and the Cispius together form the Esquiline plateau just inside the line of the Servian Wall.
In the divisions of the Septimontium Fagutal appears as an independent locality, which implies that originally "Oppius" was strictly applied to this spur except the western end. The northern tip of this western end was also called Carinae, which extended between the Velian Hill and the Clivus Pullius, looked out to the southwest, incorporated the Fagutal and was one of ancient Rome's most exclusive neighborhoods.
