A ruthenium–arene–PTA (RAPTA) complex has been supported for the first time on an inorganic solid, that is, silica‐coated ferrite nanoparticles. The resulting magnetic material proved to be a general, very efficient and easily reusable catalyst for three synthetically useful organic transformations; selective nitrile hydration, redox isomerization of allylic alcohols, and heteroannulation of (Z)‐enynols
