16 Lyncis (16 Lyn) is the 4th magnitude and brightest star in the constellation Lynx. Located approximately 74 parsecs (240 ly) distant. It was also known as Psi-10 Aurigae (ψ10 Aur).

It is a A-type main-sequence star (A2Vn),[2] a star that is currently fusing its core hydrogen. The star is suspected of being slightly variable, but this has not been confirmed.[6]
