We consider the entanglement entropy in the dS/CFT correspondence. In Einstein gravity on de Sitter spacetime we propose the holographic entanglement entropy as the analytic continuation of the extremal surface in Euclidean anti–de Sitter spacetime. Even though dual conformal field theories for Einstein gravity on de Sitter spacetime are not known yet, we analyze the freemodel dual to Vasiliev’s higher spin gauge theory as a toy model. In this model we confirm the behavior similar to our holographic result from Einstein gravity.
