The kingdom was bounded by two of the Three Sisters the rivers Barrow and Suir and the northern limit was, generally, the Slieve Bloom Mountains. The Osraige —their name means people of the deer— inhabited much of modern County Kilkenny and parts of neighbouring County Laois. To the west and south, Osraige was bounded by the River Suir, to the east the watershed of the River Barrow marked the boundary with Leinster, and to the north it extended into and beyond the Slieve Bloom Mountains. The River Nore ran through the Kingdom.
