Fore Abbey (Irish: Mainistir Fhobhair) is the ruins of a Benedictine and Early Gaelic 7th century Abbey with associated Mill, Anchorite's Cell, Holy Wells and a structure associated with St. Feichin, all situated to the north of Lough Lene in County Westmeath, adjacent to Fore village.

Architectural additions, damage by fire and dismantlement have altered the site's appearance and layout over the centuries.

The site is referenced in the Annals of Inisfallen (AI) as "Repose of Fechtnach of Fobar".

[2] In the 13th century Hugh de Lacy, Lord of Meath had built a Benedictine priory in the valley near the Gaelic Monastery.

Many of the buildings that remain today (in ruins) are from the 13th and 15th century and have been restored throughout the 20th century, making Fore Abbey and environs one of the largest group of Benedictine ruins and ecclesiastical landscape to have sojourned and remained in Ireland.
