This paper presents a novel approach to the Neutrosophic Soft Cubic Re ned Set (NSCRS), which serves as the foundation for combining the theory of soft sets, the already-existing Neutrosophic cubic set, and the Neutrosophic re ned set and Neutrosophic Soft Cubic Set. Further introduced are the internal neutrosophic soft cubic re ned set (INSCRS) and external neutrosophic soft cubic re ned set (ENSCRS), along with their various properties, including P-order, P-union, P-intersection, and R-order, R-union, and R-intersection neutrosophic soft cubic re ned set.
