A generalized procedure for the construction of the inductive limit of a family of $C^*$-algebras is proposed. The outcome is no more a $C^*$-algebra but, under certain assumptions, a locally convex quasi $^*$-algebra, named a $C^*$-inductive quasi $^*$-algebra. The properties of positive functionals and representations of $C^*$-inductive quasi $^*$-algebras are investigated, in close connection with the corresponding properties of positive functionals and representations of the $C^*$-algebras that generate the structure. The typical example of the quasi $^*$-algebra of operators acting on a rigged Hilbert space is analyzed in detail.
