Its name is derived from the Irish language. One theory is that it comes from Léana Dhearg meaning "red meadow".[http://www.logainm.ie/?text=Lenaderg&placeID=66467 Placenames Database of Ireland] However, the townland was historically called Laraderick and Laraghderick, which is believed to be derived from Láithreach Deirce.
