Xi Orionis (ξ Orionis) is a blue main-sequence star, spectral type B3V, located some 606 light years from here in the northeastern part of the constellation of Orion, well above the red giant star, Betelgeuse in the sky. It lies next to another blue main-sequence star, Nu Orionis which is somewhat closer at 514 light years.

Xi Orionis shines with an apparent visual magnitide of 4.45; its absolute magnitude is -2.0, effective temperature 21000K, and mass 9.2 (times solar). The B3 star is the primary component of a multiple-star system which has also been classified as a B3IV subgiant, although at a somewhat further distance of nearly 634 ly.
