The alkaline hydrogen evolution reaction (HER) is a key technology for hydrogen production, and polyoxometalates (POMs) have emerged as promising high‐performance catalysts owing to their unique structural and physicochemical properties. This review summarizes the mechanism of alkaline HER, the structural features, HER‐relevant properties, synthesis methods, and characterization techniques of POMs and places particular emphasis on recent advances in the application of POMs and POM‐derived materials (e.g., nitrides, sulfides) to alkaline HER. We provide an in‐depth analysis of structure–activity relationships and mechanisms of catalytic enhancement and present an outlook on future research directions to guide the design and industrial implementation of POM‐based alkaline HER catalysts.
