The greater flameback (Chrysocolaptes guttacristatus) also known as greater goldenback, large golden-backed woodpecker or Malherbe's golden-backed woodpecker, is a woodpecker species. It occurs widely in the Indian subcontinent, eastwards to southern China, the Malay Peninsula, Sumatra, western and central Java and northeast Borneo.

Recent taxonomic evidence suggests the species be split into the following species:

The greater flameback is a large woodpecker, at 33 cm in length. It is of typical woodpecker shape, has an erect crest and a long neck. Coloration is highly variable between subspecies; it always has unmarked golden-yellow to dark brown back and wings. The rump is red and the tail is black. The underparts are white with dark markings (chevrons, stripes, or bands), or light brown. The head is whitish with a black pattern, or it is yellow, brown or red. The straight pointed bill is long (longer than the head) and – like the legs and four-toed zygodactyl feet (two toes pointing forward, two backward) – lead-grey. The eyes' irides are whitish to yellow.

The adult male greater flameback always has a red crown. Females have a crown color varying between subspecies, such as black spotted with white, yellow, or brown with lighter dots. Young birds are like the female, but duller, with brown irides.

White-and-black-headed greater flameback subspecies resemble some of the three-toed Dinopium flamebacks, but are not particularly closely related. Unlike the black-rumped flameback (D. benghalense) and the common flameback (D. javanense), the greater flameback's dark moustache stripes are divided by white (making them inconspicuous at a distance); except in stricklandi, their hindneck is white (not black), and even in the Sri Lankan birds the dark colour does not extend to between the shoulders as it does in Dinopium; consequently, when seen from behind the black-and-white-headed greater flamebacks outside Sri Lanka show a white neck bordered with black on the sides, while the Dinopium species have a black neck and upper back, with thin white borders to the neck. Those flamebacks are also smaller (though this is only reliable in direct comparison), have a bill that is shorter than the head, and dark irises.
