Kilglass or Kilglas[1] (Irish: Cill Ghlas, meaning 'green church')[2] is a rural townland in County Sligo, Ireland, in the hinterland of Enniscrone.

[2] The area is the location of an Anglican church, built in 1829 with funding provided by the Board of First Fruits, and renovated in 1996.

The parish is in the Church of Ireland Diocese of Tuam, Killala and Achonry.

[citation needed] The building is named after the local Mac Fhirbhisigh clan, who were bardic chroniclers of medieval Ireland and associated with the nearby the townland of Lacken.

[citation needed] Although Cill Ghlas is the official Irish-language version of the name Kilglass today,[2] it is believed that the most likely derivation is that it is a corruption of Cill Molaise (St Molash's church).
