Keenaght (locally [ˌkʲiːnəx], from Irish Caonach 'mossy place'[2]) is a townland lying within the civil parish of Kilcronaghan, County Londonderry, Northern Ireland.

[4][5] As part of Kilcronaghan civil parish, Keenaght also lies in the historic barony of Loughinsholin.

The present name of this townland, Keenaght, is very likely a reformed analogy of the neighbouring barony of Keenaght, with scribal errors adding a t to the end of anglicisations of its name such as with Tonaght in the neighbouring parish of Ballynascreen, which actually derives from Tonach.

[2] It is more reasonably suggested that Keenaght derives from the synonym Coanna with the adjectival suffix -ach added to it.

[2] This derivation is supported by the majority of earlier recorded forms.
