County Mayo (Irish: Contae Mhaigh Eo) is a county in Ireland in the province of Connacht.

Irish Townlands is an OpenStreetMap project that maps all County Mayo known Baronies, Civil Parishes, Electoral Divisions, Townlands, and Subtownlands.

Currently, Irish Townlands links to the free 1901 and 1911 Ireland Census and to Griffith’s Valuation where records exist for a townland or subtownland.
