Wound healing is a long‐term, multistage biological process that includes hemostasis, inflammation, proliferation, and tissue remodeling and requires intelligent designs to provide comprehensive and convenient treatment. The complexity of wounds has led to a lack of adequate wound treatment materials, which must systematically regulate unique wound microenvironments. Hydrogels have significant advantages in wound treatment due to their ability to provide spatiotemporal control over the wound healing process. Self‐assembling peptide‐based hydrogels are particularly attractive due to their innate biocompatibility and biodegradability along with additional advantages including ligand‐receptor recognition, stimulus‐responsive self‐assembly, and the ability to mimic the extracellular matrix. The ability of peptide‐based materials to self‐assemble in response to the physiological environment, resulting in functionalized microscopic structures, makes them conducive to wound treatment. This review introduces several self‐assembling peptide‐based systems with various advantages and emphasizes recent advances in self‐assembling peptide‐based hydrogels that allow for precise control during different stages of wound healing. Moreover, the development of multifunctional self‐assembling peptide‐based hydrogels that can regulate and remodel the wound immune microenvironment in wound therapy with spatiotemporal control has also been summarized. Overall, this review sheds light on the future clinical and practical applications of self‐assembling peptide‐based hydrogels. The main self‐assembling peptide‐based systems, the advantages of self‐assembling peptide‐based hydrogels, and the rational design of peptide‐based materials for different stages of wound healing are reviewed. Advanced self‐assembling peptide‐based materials that can be applied in spatiotemporally controllable, multifunctional wound healing and regulate/remodel the wound microenvironment are discussed. Prospects and challenges related to peptide‐based hydrogels for wound healing are also highlighted.
