All‐inorganic cesium lead halide perovskites have emerged as promising optoelectronic materials with excellent photophysical properties and great potential in a variety of applications. In parallel with the most investigated CsPbX₃, its derivates, Cs₄PbX₆ and CsPb₂X₅, with low‐dimensional‐networked structures have also attracted great attention. In this review, recent advancements on the low‐dimensional‐networked cesium lead halide perovskites (Cs₄PbX₆ and CsPb₂X₅) are reviewed systematically. The optical properties and direct controllable synthesis methods are first introduced. The transformation between Cs_xPb_yX_z and their hybridization are then presented, followed by their wide applications. Finally, challenges and prospects of this class of perovskites are introduced.
