The chowchilla (Orthonyx spaldingii) is a passerine bird in the family Orthonychidae.

In their 1999 study, Schodde and Mason recognise two adjoining subspecies, O. s. spaldingii and O. s. melasmenus with a zone of intergradation.

Males and females largely dark brown with white eye-ring, tail-feather shafts extend as spines beyond feather-vanes; males with white throat, breast and belly; females with bright rufous throat and upper breast, white lower breast and belly.

The chowchilla is restricted to upland and lowland tropical rainforests of north-eastern Queensland.

Builds a bulky, dome-shaped stick-nest with a clutch of one, possibly sometimes two, white eggs.
