90 Tauri (90 Tau) is a star in the zodiac constellationofTaurus,^[9] located 144 light-years away from the Sun.^[1] It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.27.^[2] 90 Tauri is a member of the Hyades cluster and is listed as a double star.

This is an A-type main-sequence star with a stellar classification of A6 V.^[3] It has 2.1 times the mass of the Sun and 2.8 times the Sun's radius.^[8] An orbiting companion was announced in 2014. This is probably a spectral class K4V star with an estimated orbital period of at least 84 days. The primary is being orbited by a debris disk.^[10]
