Alsodes monticola (common name: island spiny-chest frog) is a species of frog in the family Alsodidae. It is found in southern Chile and western Santa Cruz Province, Argentina,[1] though its presence in Argentina is disputed. Its habitat preferences are not known, but the region of the type locality (the island of Inchy, in the Chonos Archipelago[1]) has tundra and islands of Nothofagus forest.
