Kilmacrehy is part of the historical Barony of Corcomroe.
It is about 4 miles (6.4 km) to the west of Ennistymon.
It is on the north shore of Liscannor Bay on the western coast of Clare.
The parish makes up the peninsula that extends to the basaltic promontory called Hag's Head.
From this point the Cliffs known as the Cliffs of Moher run to the northeast gradually rising to O'Brien's Tower, where they are about 600 feet (180 m) above sea level.

Dough townland is the only part of the parish that lies on the south bank of the estuary of the Inagh River.

The parish once had the alias of Quoranna, meaning "the distinct projection", an allusion to the imposing cliffs.

An 1837 account says that the parish contained 5,492 acres (2,223 ha), as applotted under the tithe act, including pasture and arable land fertilized with seaweed.

An 1845 account gives the parish a total area of 7,403 acres (2,996 ha), and dimensions of about 3.75 by 3.5 miles (6.04 by 5.63 km).

Today, part of the town of Lahinch is located in the townland of Dough.
