Please note, this list is by no means complete, please update it as you find more redlinks relating to Ireland.
Note in reply to this request: I created sortable lists of townlands for all the counties in 2010 (someone else created the lists for the six counties of Northern Ireland). See: Category:Lists of townlands of Ireland, and view one example: List of townlands of County Dublin. — O'Dea (talk) 04:36, 24 December 2020 (UTC)
