The Bayer designation Phi Orionis (φ Ori, φ Orionis) is shared by two star systems in the constellation Orion.

The two stars are separated by approximately 0.71° in the sky.

Etymology

Both of φ Ori and λ Ori were Al Haḳʽah, "a White Spot".

The similar composition were found in Chinese astronomy, known as 觜宿 (Zī Sù), meaning Turtle Beak (asterism), Consequently, both of φ Ori themselves is known as 觜宿二 (Zī Sù èr .) (for φ1Ori) and 觜宿三 (Zī Sù sān .) (for φ2Ori)
