Canis Major (pronounced ˈkeɪnɪs ˈmeɪdʒər) is the Latin name of a constellation situated close to the celestial equator. As such, it is at least partly visible from both hemispheres in certain times of the year.

In English language this constellation is also known as "The Greater dog" while in astronomical texts and literature this constellation is often abbreviated as "CMa" (according to the standard of the International Astronomical Union - IAU) or as "CMaj" (according to a naming convention used by NASA).

The Latin genitive of the constellation name is "Canis Majoris" (pronounced ˈkeɪnɪs məˈdʒɒrɪs) and it is used to identify some of the brightest stars in this constellation based on the Bayer or Flamsteed star naming convention. For instance: α Canis Majoris (the brightest star of Canis Major based on the Bayer catalog); or 23 Canis Majoris (the 23th star in the constellation of Canis Major based on the Flamsteed catalog).

Canis Major is below the horizon from Greenwich, UK.
