Ard na Caithne (]), meaning height of the arbutus or strawberry tree, sometimes known in English as Smerwick, is a bay and townland in County Kerry in Ireland. One of the principal bays of Corca Dhuibhne, it is located at the foot of An Triúr Deirfiúr and Mount Brandon. Bounded by the villages of Baile an Fheirtéaraigh, Baile na nGall and Ard na Caithne itself, the area is what has been known as the Fíor-Ghaeltacht, or true Gaeltacht (an area in which the Irish language is the official and principal language).
