The brown-backed needletail (Hirundapus giganteus), or brown needletail, is a large swift.

These birds have very short legs which they use only mainly for clinging to vertical surfaces. They never settle voluntarily on the ground and spend most of their lives in the air, living on the insects they catch in their beaks.

These swifts are resident breeders in hill forests in southern India and southeast Asia, extending to the Greater Sunda islands of Indonesia and Palawan in the southern Philippines.

The Hirundapus needletailed swifts get their name from the spined ends of their tail, which is not forked as in the Apus typical swifts. The brown-backed needletail has more prominent tail spines than in other needletail species.
