Abstract: ABSTRACT Light‐addressable electrochemistry (LAE) has emerged as a transformative technique for achieving spatially resolved electrochemical control without the constraints of physical micro‐wiring or the low throughput of scanning‐probe techniques. Exploiting the photoelectric effect on an unstructured semiconductor surface, LAE enables the precise confinement of redox reactions and potential mapping via dynamic optical patterns. This review provides an in‐depth appraisal of recent breakthroughs in the field. We evaluate the latest strategies in electrode material engineering, focusing on optimizing charge separation and surface kinetics to enhance spatial resolution and sensitivity. Furthermore, we survey the expanding application landscape, including multiplexed biosensing, bioimaging, and maskless electrochemical lithography. By critically addressing current limitations, this article offers a forward‐looking perspective on integrating LAE with other systems, highlighting its potential to redefine the boundaries of analytical chemistry and materials science.
