Circinus is one of fourteen southern constellations created by Nicolas-Louis de Lacaille in 1756 as a result of his observations of ten thousand southern stars, but not introduced to the public until the posthumous publication of his work in 1763.

 Stars that have common names often have multiple names, so the common names shown (if any) cannot be considered authoritative. Right ascension and declination are given in 2000.0 coordinates.
