The commune of Maré is made up of Maré Island and the much smaller Dudune Island, which lie among the Loyalty Islands, to the northeast of New Caledonia's mainland.
O concello de Maré componse da illa de Maré e a moito máis pequena illa de Dudune, que se atopan entre as illas da Lealdade, ao nordés da parte continental de Nova Caledonia.
