Multifunctional　hydrogels　hold　significant　promise　for　promoting　the　healing　of　infected　wounds　but　often　fall　short　in　inhibiting　antibiotic-resistant　pathogens,　and　their　clinical　translation　is　limited　by　complex　preparation　processes　and　high　costs.　In　this　study,　a　multifunctional　hydrogel　is　developed　by　combining　metal-phenolic　networks　(MPNs)　formed　by　tannic　acid　(TA)　and　gallium　ions　(Ga3+)　with　chitosan　(CS)　through　a　simple　one-step　method.　The　resulting　CS-TA-Ga3+　(CTG)　hydrogel　is　cost-effective　and　exhibits　desirable　properties,　including　injectability,　self-healing,　pH　responsiveness,　hemostasis,　antioxidant,　anti-inflammatory,　and　antibacterial　activities.　Importantly,　the　CTG　hydrogels　are　effective　against　antibiotic-resistant　pathogens　due　to　the　unique　antibacterial　mechanism　of　Ga3+.　In　vivo　studies　demonstrate　that　the　CTG　hydrogel　promotes　follicle　formation　and　collagen　deposition,　accelerating　the　healing　of　infected　wounds　by　inhibiting　blood　loss,　suppressing　bacterial　growth,　and　modulating　the　inflammatory　microenvironment.　These　findings　highlight　the　CTG　hydrogel＇s　potential　as　an　advanced　and　translational　dressing　for　enhancing　the　healing　of　infected　wounds.
