Metal halide perovskites (MHPs) have excellent optoelectronic and photovoltaic applications because of their cost‐effectiveness, tunable emission, high photoluminescence quantum yields, and excellent charge carrier properties. However, the potential applications of the entire MHP family are facing a major challenge arising from its weak resistance to moisture, polar solvents, temperature, and light exposure. A viable strategy to enhance the stability of MHPs could lie in their incorporation into a porous template. Metal‐organic frameworks (MOFs) have outstanding properties, with a unique network of ordered/functional pores, which render them promising for functioning as such a template, accommodating a wide range of MHPs to the nanosized region, alongside minimizing particle aggregation and enhancing the stability of the entrapped species. This review highlights recent advances in design strategies, synthesis, characterization, and properties of various hybrids of MOFs with MHPs. Particular attention is paid to a critical review of the emergence of MHP@MOF for comprehensive studies of next‐generation materials for various technological applications including sensors, photocatalysis, encryption/decryption, light‐emitting diodes, and solar cells. Finally, by summarizing the state‐of‐the‐art, some promising future applications of reported hybrids are proposed. Considering the inherent correlation and synergic functionalities of MHPs and MOFs, further advancement; new functional materials; and applications can be achieved through designing MHP@MOF hybrids. This review critically summarizes metal halide perovskites (MHP) encapsulated into the pores of the metal‐organic framework (MOF) matrices (MHP@MOF). Recent progress in synthesis, design, properties as well as critical challenges and potential applications in this field is discussed.
