The concept of exact sequences has been widely used in ring and module theory. The U-exact sequence and the V-coexact sequence are generalizations of the exact sequence. Besides it, rough set theory has been implemented in several algebraic structures such as groups, rings, modules, and others. In this research, a rough V-coexact sequence will be constructed in the rough group and its characteristics. Furthermore, we will give the relationship between the V-coexact sequence in the group and the rough V-coexact sequence in the rough group.
