Here we report the realization of 2D superconductivity in the newly-synthesized niobium dichalcogenides-based bulk superlattices Ba$_{0.75}$ClNbS$_{2}$ and Ba$_{0.75}$ClNbSe$_{2}$, which consists of the alternating stacking of monolayer $H$-NbS$_{2}$ (or $H$-NbSe$_{2}$) and monolayer inorganic insulator spacer Ba$_{0.75}$Cl.
