This is a sortable table of the approximately 3,424 townlands in County Mayo, Ireland.[1] [2] as was the case prior to 1873.
Duplicate names occur where there is more than one townland with the same name in the county. Names marked in bold typeface are towns, and the word Town appears for those entries in the Acres column.
