Canopus (), also designated Alpha Carinae (α Carinae, abbreviated Alpha Car, α Car), is the brightest star in the southern constellation of Carina, and the second-brightest star in the night-time sky, after Sirius. Canopus's visual magnitude is −0.74, and it has an absolute magnitude of −5.71.

Canopus is a bright giant of spectral type A9, so it is essentially white when seen with the naked eye. It is located in the far southern sky, at a year 2000 declination of −52° 42′ and a right ascension of 06h 24.0m.

Its name is generally considered to originate from the mythological Canopus, who was a navigator for Menelaus, king of Sparta (see below).
