The White-crowned Parrot is 24 cm long and weighs 220 g. The adult male has a white forehead and crown, the feature which, likened to an old man’s white hair, gave rise to the specific name senilis. The throat is white, and the rest of the head, neck and breast are dull dark blue. The belly is light green, and the upperparts are dark green, with a yellow-olive shoulder patch. In flight, the blue underwings and red vent are conspicuous features.

The female White-crowned Parrot is similar to the male, but the blue plumage fades into scaling on the lower breast and the shoulder patch is duller. Young birds have little blue on the head and neck or red on the undertail, and the crown feathers are green edged with white.
