Aclare (Irish: Áth an Chláir, meaning 'ford of the plain') is a village in County Sligo, Ireland, and the main village in the parish of Kilmactigue. Formerly, the village of Aclare was not part of the same-named townland, but straddled the border of the adjacent townlands of Lislea and Carns, though later the borders of the townland were extended to encompass the village. The village is situated on the Inagh (also spelt "Eignagh") river, a tributary of the Moy.

The village, as well as the surrounding townlands, is known for its musicians and singers, particularly in Irish traditional music.

An annual St Patrick's Day parade is held in the area.

Belclare Castle (Irish: Béal an Chláir, meaning 'mouth of the plain') is a ruined castle located within sight of the village. The castle is located about half a mile west of Kilmactigue Chapel and was originally built and inhabited by the O'Hara clan in the 15th century.
