The NGC 4631 Group is a poorly defined group of galaxies, about 25 million light-years from Earth in the Coma Berenices and Canes Venatici constellations.

The NGC 4631 Group is one of many that lie within the Virgo Supercluster.

[3] Aside from these four galaxies, however, the determination of group membership is quite variable.

The group lies in a relatively crowded part of the sky near the Virgo Cluster, so exact determination of the group membership is extremely difficult.

[2] Additionally, it is unclear as to whether the galaxies near NGC 4631 and NGC 4656/NGC 4657 form one large group or two smaller groups.
