Parknabinnia Wedge Tomb, Prehistoric wedge tomb in County Clare, Ireland.

Parknabinnia is a wedge tomb on Roughan Hill, built of large upright stones with a roof slab about three metres long covered by a layer of earth and grass. Its wedge shape is only slightly pronounced, and the chamber is closed at one end while the other end leaves a small entrance. Only the chamber survives; the surrounding cairn is partly preserved on one side.

The Roughan Hill tombs, including this one, are tentatively dated to 2300–2000 BC. No wedge tomb in the Burren has been excavated, so the dating rests on comparison rather than finds. The tomb's wedge shape, widest at the southwest end facing the setting sun, is typical of the type.

The name Parknabinnia comes from Irish Páirc na Binne. The tomb sits on Roughan Hill, which holds the largest concentration of the eighty wedge tombs still standing in County Clare. The site lies on private land but can be seen from the nearby road.
