Abstract Cellulose-based hydrogels have emerged as promising materials in a wide range of applications owing to their inherently renewable, biocompatible, and biodegradable characteristics. The present chapter addresses advances in the synthesis methods of cellulose-based hydrogels from native cellulose, cellulose derivatives, or composites and focuses on the design and preparation of reversible crosslinked cellulose-based hydrogels featured with self-healing or dynamic stimuli response. Dynamic chemistry, including reversibly chemical and physical crosslinking methods, provides a fascinating strategy for the fabrication of cellulosebased hydrogels through the formation of reversible dynamic covalent bonds or non-covalent interactions, respectively. Moreover, we provide the future outlook for the guidance of fruitful explorations of hydrogels based on cellulose and their derivatives to expand their further advancement.
