Psi7 Aurigae, Latinized from ψ7 Aurigae, is a star in the northern constellation of Auriga. It is a dim, naked eye star with an apparent visual magnitude of 5.02. Based upon Gaia Data Release 2 parallax values, it is approximately {{Convert|330|ly|pc|abbr=off|lk=on}} from Earth.

ψ7 Aurigae is a giant star with a stellar classification of K3 III.[4] The measured angular diameter of this star, after correction for limb darkening, is {{nowrap|1.96 ± 0.04 mas}}.[20] At its estimated distance, this yields a physical size of about 24 times the radius of the Sun.[12] The outer envelope has an effective temperature of 4,300,[14] giving it an orange colour and a classification as a K-type star.[24] Although cooler than the sun, its larger size means that it is more luminous, emitting in total 217 times as much electromagnetic radiation.
