Psi2 Piscium (ψ2 Piscium) is a white-hued star in the zodiac constellation of Pisces. It is faintly visible to the naked eye, having an apparent visual magnitude of +5.56. Based upon an annual parallax shift of 8.66 mas as seen from Earth, it is located about 380 light years from the Sun. It has a peculiar velocity of , indicating it is a runaway star.
This is a suspected binary star system, with a companion star at an angular separation of along a position angle of from the primary, as of 2008. This corresponds to a projected separation of . The brighter component is an A-type main sequence star with a stellar classification of A3 V. The system is a source of X-ray emission with a luminosity of , which is most likely originating from the cooler companion since A-type main sequence stars are not expected to be magnetically active.
