Iota Tauri (ι Tau, ι Tauri) is a star in the constellation Taurus and an outlying member of the Hyades star cluster.

Iota Tauri is a class A7V[3] white A-type main sequence dwarf with an apparent magnitude of +4.62.[2] It is approximately 173 light years from Earth based on parallax.[1]

It has been reported as a double star with two components at separation 0.1", both of type A7V and magnitude 5.4.[9][10]
