Kilmoon (Irish: Cill Mhúine[1]) is a civil parish of County Clare, Ireland, 7 miles (11 km) north of Ennistymon.

There is a Romanesque standing stone in the area on the site of a ruined church, St Mogua.

[3] Kilmoon fell under the poor law union of Ennistymon in the barony of Burren, and ecclesiastically belonged to the Diocese of Kilfenora in the Province of Cashel as of 1810.

[2] The civil parish of Kilmoon is in the northwestern part of the county and is bordered by Rathborney to the northeast, Killeany to the east, Kilfenora to the southeast, Killilagh to the southwest, and Killonaghan to the northwest.

The property is mentioned several times in 16th-century documents, when inhabitants of the castle were pardoned for committed crimes.
