Lecanvey or Leckanvy is a seaside village in County Mayo, Ireland, between Westport and Louisburgh, about 2 km west of Murrisk. It has a small beach with Lecanvey Pier. To the south is Croagh Patrick. To the west is Clare Island.
The Lecanvey Community Alliance was constituted in 2006 to improve the environment of the parts of the area which do not fall into the catchment area of Murrisk or of Louisburgh. Local concerns include improvement of roads and pavements, speed limits, litter control, hedging and mowing, and place-names and area signage.
