Psi³ Aurigae, Latinized from ψ³ Aurigae, is a single, blue-white hued star in the northern constellation of Auriga. It is dimly visible to the naked eye with an apparent visual magnitude of +5.20. Based upon an annual parallax shift of {{nowrap|2.38 ± 0.39 mas}} as seen from the Earth, it is approximately {{Convert|1370|ly|pc|abbr=off|lk=on}} distant from the Sun.

This is a B-type giant star with a stellar classification of B8 III. It has about 4.2 and is spinning with a relatively high projected rotational velocity of 118 km/s. The star is radiating 1,624 times the Sun's luminosity from its photosphere at an effective temperature of 13,361 K.
