Hybrid organic–inorganic perovskite (HOP) spintronics aims to make full use of the properties of electron spin. HOP spintronics has recently emerged as a promising field of research because it provides a new precisely manipulable degree of freedom. The flourishing development activity in this field has benefited from the unique intrinsic spin‐related optoelectronic properties of HOPs, which include triplet formation, a large Stark effect, the magneto‐optical effect, polarized light‐related effects, and complex light emission characteristics, which offer the possibility of providing a new way to control the performance of integrated optoelectronic devices through spin interactions between photons and electrons. Along with the continuous improvements in the theoretical research into HOP spintronics, large numbers of novel optoelectronic devices have been proposed and demonstrated experimentally and have shown great potential for fabrication of next‐generation, high‐performance integrated optoelectronic chips. This review provides an overview of the fundamental principles, novel spin‐generated physical effects, and diverse structures of HOP spintronics systems, along with the applications of HOP spintronics in optoelectronic devices, while also undertaking a general review of the remaining challenges and proposing possible development directions that require further study for the application of HOP spintronics to integrated optoelectronic devices.
