The synthesis of highly microporous, epoxy‐functionalized porous organic polymers (ep‐POPs) by a one‐pot, catalyst‐free Diels–Alder cycloaddition polymerization is reported. The high oxygen content of ep‐POPs offer efficient hydrogen‐bonding sites for water molecules, thus leading to high water‐uptake capacities up to 39.2–42.4 wt % under a wide temperature range of 5–45 °C, which covers the span of climatic conditions and manufacturing applications in which such materials might be used. Importantly, ep‐POPs demonstrated regeneration temperatures as low as 55 °C, as well as excellent water stability, recyclability, and high specific surface areas up to 852 m 2 g −1 .
