List of monastic houses in County Longford
In this article, smaller establishments such as monastic cells and notable monastic granges (particularly those with resident monks) and camerae of the military orders of monks (Knights Templars and Knights Hospitallers) are included. The numerous monastic hospitals per se are not included here unless at some time the foundation had, or was purported to have, the status or function of an abbey, priory, friary or preceptory/commandery.
Communities/provenance: shows the status and communities existing at each establishment, together with such dates as have been established as well as the fate of the establishment after dissolution, and the current status of the site.
Formal name or dedication: shows the formal name of the establishment or the person in whose name the church is dedicated, where known.
Alternative names: some of the establishments have had alternative names over the course of time. In order to assist in text-searching such alternatives in name or spelling have been provided.

- S. Lewis, Topographical Dictionary of Ireland, 1837, i, p.283
- Mervyn Archdall, Monasticon Hibernicum, 1786, p.444 gives St Idus having a foundation here, which was actually at Aghade (Ath-fadat—"long ford"), County Carlow
- J. J. McNamee, DD, History of the Diocese of Ardagh, 1954, pp.34-5, 541
- James Ware, De Hibernia et Antiquitatibus ejus, 1654 edition, p.172 and others, confuse Saints Island and Inis Aingin, the latter being founded by St Ciaran. Louis Augustin Alemand, Monasticum Hibernicum, translated and edited by John Stevens, 1722, pp.49, 50, has a foundation by Ciaran at both locations, which is possible, though Inis Aingin alone is mentioned in the Life of St Ciaran: Vitae Sanctorum Hiberniae, edited by Charles Plummer, 1910, i, pp.210, 211
