The lined forest falcon (Micrastur gilvicollis) is a species of bird of prey in the Falconidae family. It is endemic to humid forest in the western and northern Amazon Basin. Populations found in the south-eastern Amazon Basin (south of the Amazon River and east of the Madeira River) were formerly included in this species, but were described as a new species, the cryptic forest falcon, in 2003.
