In mathematics, in the field of group theory, a subgroup of a group is called c-normal if there is a normal subgroup of such that and the intersection of and lies inside the normal core of .

For a weakly c-normal subgroup, we only require to be subnormal.

Here are some facts about c-normal subgroups:
