**Abstract : **

The notion of neutrosophic ring R(I) generated by the ring R and the indeterminacy component I was introduced for the ﬁrst time in the literature by Vasantha Kandasamy and Smarandache in.12 Since then, fur-ther studies have been carried out on neutrosophic ring, neutrosophic nearring and neutrosophic hyperring see.1, 3, 4, 6–8 Recently, Smarandache10 introduced the notion of reﬁned neutrosophic logic and neutrosophic set with the splitting of the neutrosophic components < T, I, F > into the form

< T1, T2, . . . , Tp; I1, I2, . . . , Ir; F1, F2, . . . , Fs > where Ti, Ii, Fi can be made to represent different logical notions and concepts. In,11 Smarandache introduced reﬁned neutrosophic numbers in the form (a, b1I1, b2I2, . . . , bnIn) where a, b1, b2, . . . , bn ∈ R or C. The concept of reﬁned neutrosophic algebraic structures was introduced by Agboola in5 and in particular, reﬁned neutrosophic groups and their substructures were studied. The present paper is devoted to the study of reﬁned neutrosophic rings and their substructures. It is shown that every reﬁned neutrosophic ring is a ring.

For the purposes of this paper, it will be assumed that I splits into two indeterminacies I1 [contradiction (true (T) and false (F))] and I2 [ignorance (true (T) or false (F))]. It then follows logically that:
