Gamma Comae Berenices, Latinized from γ Comae Berenices, is a single, orange-hued star in the northern constellation of Coma Berenices. It is faintly visible to the naked eye, having an apparent visual magnitude of 4.36. Based upon an annual parallax shift of 19.50 mas as seen from Earth, its distance can be estimated as around 167 light years from the Sun. The star is moving away from the Sun with a radial velocity of +3 km/s.

This is an evolved K-type giant star with a stellar classification of K1 III Fe0.5.

R. H. Allen's Star Names attributes the name Al Ḍafīrah to this star, from an Arabic name for the Coma Star Cluster. In Chinese astronomy, it is identified as Lángwèiyī (郎位一), meaning it is the first star of the asterism Lángwèi (郎位, Officers of the Imperial Guard).
