Apus (I Latin: bird of paradise or swallow, from Greek: απους, meaning "no-feet") is a faint southern constellation, not visible to the ancient Greeks. The constellation was one of twelve constellations created by Pieter Dirkszoon Keyser and Frederick de Houtman between 1595 and 1597, and it first appeared in Johann Bayer's Uranometria of 1603.

Notable deep sky objects

Apus has several impressive clusters, NGC 6101 and IC 4499, as well as a very unusual nebular structure IC 4633.
