ABSTRACT=<p>Environmental pollution and energy shortage make the development of clean energy more and more urgent. As a kind of clean renewable energy, hydrogen has attracted more attention recently. WO<sub>3</sub>-based materials have emerged as one of the most promising candidates for electrocatalytic hydrogen evolution reaction (HER) due to their attractive electrocatalytic activity, low cost, as well as electrochemical durability. In this minireview, we systematically provide an overview of WO<sub>3</sub>-based materials applied for HER, including pure WO<sub>3</sub>, doped WO<sub>3</sub>, and WO<sub>3</sub>-based composite materials. Furthermore, the strategies to enhance their electrocatalytic performance are summarized and discussed, such as morphological engineering, doping, as well as compositing with other materials. Finally, the limitation and challenges of WO<sub>3</sub>-based materials for HER and their prospects for future research are proposed. We believe that this minireview will be favorable for scientists to seek more promising HER electrocatalysts.</p>
