The Masafuera rayadito (Aphrastura masafuerae) is a rare bird endemic to Alejandro Selkirk Island (Isla Más Afuera, Outermost Island) in the Juan Fernández Islands. The species is a member of the ovenbird family and only one of three species in the rayadito genus. The species' natural habitat is humid montane scrub, dominated by tree ferns (Dicksonia externa) and ferns (Lophosoria quadripinnata) between 800–1300 m above sea level (though they will descend lower during the austral winter).
