Hooded Grosbeak is a large, stocky finch with a very thick, pale bill and a relatively short tail. The species is sexually dichromatic. The male has an entirely black head (the "hood") and black wings with contrasting silvery gray tertials. The back is yellow olive, and the underparts are yellow. The plumage of the female is primarily grayish yellow or grayish olive, with a black crown; the wing pattern of the female is similar to that of the male.
Male Hooded Grosbeaks are distinctive and are unlikely to be confused with any other species. Black-headed Siskin (Spinus notatus) is much smaller with a smaller dark bill, lacks the pale tertials, and has a yellow wingbar. Female and juvenile Hooded Grosbeaks may be mistaken for Evening Grosbeaks (Coccothraustes vespertinus). In general, female Evening Grosbeaks are grayer, and lack the black cap Calls of both species also distinctive.

Adult male: Entire head and throat are black. The mantle, back, and scapulars are yellow olive to light olive green; lower back and rump brighter yellow. Upper tail coverts black or yellow with longer feathers edged and tipped in black. Tail is black, with a shallow fork. Wing coverts and remiges black, except for grayish or silvery gray inner greater primary coverts and tertials (the tertials edged with yellow in fresh plumage). Also, some of the outer primaries (fourth through seventh) sometimes with a white spot at base. Underparts bright yellow; tibial feathering black or blackish but edged with yellow
Adult female: Black cap extends from the forehead to crown (including sides of crown) and nape with a dusky black chin and black lores. Face grayish olive or pale olive green washed with yellow. Mantle, back and scapulars are olive to olive green with a wash of yellow (especially in fresh plumage). The rump paler yellow.
