The Brown Trembler (Cinclocerthia ruficauda) is a species of bird in the Mimidae family.

It is found in the Lesser Antilles where it breeds on Saba, St. Kitts, Nevis, Montserrat, Guadeloupe, Dominica and St. Vincent. It formerly occurred on St. Eustatius. Northern birds from Guadeloupe northwards may represent a separate species (C. pavida) from those on Dominica and St. Vincent.

Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest.
