p Puppis (HD 60863) is a star system the constellation Puppis. This system consists of a B8V (blue main-sequence) star and a secondary star at 7.4 AU, much smaller than the primary, as well as farther companions. Its apparent magnitude is 4.65 and it is approximately 222 light years away based on parallax.

In addition to the inner pair, there are the distant companions HIP 36890, at apparent magnitude 7.83 and projected separation of 38,700 AU, which is itself an astrometric binary, and a faint white dwarf at a distance of 1,300 AU. This make p Puppis a five-star system.
