The satinbirds or cnemophilines, are a family, Cnemophilidae of passerine birds which consists of four species found in the mountain forests of New Guinea.

[1] The family name "Cnemophilidae" consists of the words knemos for "mountain/slope" and philos for "lover", referring to the species' fondness for mountain slopes.

Unique for the satinbirds, the males also have bulbous wattles, or lobes, on the top of the bill that are a pale sky blue in color.

Satinbirds have weak, non-manipulative feet, wide gapes (at one time they were given the name "wide-gaped bird-of-paradise"), as well as an unossified nasal region.

Almost nothing is known of its biology, and it seems scarce and local within the patches of habitat along the central ranges east to the base of the Huon Peninsula.
