Nu Canis Majoris (ν Canis Majoris) is a binary star in the constellation Canis Major. It is visible to the naked eye with a combined apparent visual magnitude of 5.7. Based on parallax shift of 12.366 mas as seen from our orbit, this system is approximately 264 light years from the Sun.

As of 2011, the pair had an angular separation of 17.29 arc seconds along a position angle of 264.2°. The yellow hued magnitude 5.87 primary, component A, is an evolved G-type giant star with a stellar classification of G8 III. Its magnitude 7.61 companion, component B, is a yellow-white hued F-type main sequence/subgiant hybrid with a class of F3 IV-V.
