High‐performance electrocatalysts have been deeply investigated and widely explored to improve the energy conversion efficiency in advanced electrochemical technologies. As a vital rare‐earth oxide, CeO₂ has shown great promise in catalysis for its feasible redox feature, high oxygen storage capacity, abundant surface oxygen defects, and structural robustness. The structural characteristics will boost the electrocatalytic activity and durability of CeO₂‐based hybrids. In this Review, relevant research results focusing on recent hybrid materials between CeO₂ and other functional species, including metal, metal oxides/hydroxides, metal sulfides and phosphides, towards the oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and nitrogen reduction reaction (NRR) are summarized. This Review also highlights the key role of CeO₂ and the structural design strategies in the hybrid electrocatalysts, including ion doping, interface and defect engineering, electronic structure optimization, and morphology control for catalytic output enhancement. Lastly, some scientific challenges and perspectives have been proposed, aiming to promote the development of other CeO₂‐based hybrids for energy related electrocatalysis.
