Celeus is a genus of bird in the woodpecker family, Picidae, found in tropical and subtropical forests and woodlands of Central and South America. The genus contains 13 extant species. One, Kaempfer's woodpecker (C. obrieni), was believed to be extinct until a specimen was caught in 2006.

The species in the genus are medium-sized, 19–32 cm (7.5–12.6 in) in length (with chestnut woodpecker (Celeus elegans) the longest), and weigh between 63 and 172 g (2.2 and 6.1 oz). They have limited plumage colour with the head and crest mainly lighter in colour. The feet, tail, tongue and bill of the birds in the genus are adapted for the specialised resources required for its survival and reproduction (for example breeding sites and large food supplies). They are native residents and do not migrate. They are generally insectivorous but will eat seeds and fruits. The birds are monogamous with both sexes sharing nest and brooding care. Some species nest communally. Many live near humans but are seen as destructive in agricultural areas.
