χ Puppis, Latinised as Chi Puppis, (HD 65456) is a class A5II (white bright giant) star in the constellation Puppis. Its apparent magnitude is 4.79 and it is approximately 1210 light years away based on parallax.
In his star atlas Neue Uranometrie, Friedrich Wilhelm Argelander labelled this star as χ Argo. It was probably labelled as χ by Bayer in the original Uranometria, although Bayer's chart is somewhat fanciful. Nicolas-Louis de Lacaille changed Bayer's designations in Argo Navis and applied χ to the star now called χ Carinae.
