There has been phenomenal recent progress in computing CFT entanglement and Renyi entropies, holographically and otherwise. We extend these investigations to the higher spin regime—where sensible notions of geometry are sorely lacking—by computing ground state Renyi entropy in certain classes of holographic CFTs with higher spin symmetry. Our calculations are performed at both classical and one-loop level, from gravity and CFT . Along the way, we establish perturbative methods for computing Renyi entropy in any CFT , with or without higher spin symmetry and in various spacetime dimensions.
