A supramolecular hydrogel is formed by a water‐soluble polymer cross‐linked with host–guest inclusion complexes between cyclodextrin and ferrocene. Dissociation and re‐formation of inclusion complexes by redox stimuli lead to macroscale expansion and contraction of the hydrogel. The gel is utilized as a redox‐responsive actuator and the mechanical work done is evaluated.
