Beta Coma Berenices (β Comae Berenices / β Com) is a main sequence dwarf star in the constellation of Coma Berenices. The Greek letter beta (β) usually indicates that the star has the second highest visual magnitude in the constellation. In actuality, however, it is slightly brighter than α Comae Berenices.

This star is similar to our own Sun, being only slightly larger and brighter in absolute magnitude. The surface of this star has a measured activity cycle of 16.6 years (compared to 11 years on our Sun.) It may also have a secondary activity cycle of 9.6 years. At one time it was thought that this star may have a spectroscopic companion. However this was ruled out by means of more accurate radial velocity measurements. No planets have yet been detected around this star, and there is no evidence of a dusty disk.
