Using the proposal for holographic entanglement entropy in higher derivative gravities, we
compute holographic entanglement entropy for the conformal gravity in four dimensions which
turns out to be finite. However, if one subtracts the contribution of the four dimensional Gauss-
Bonnet term, the corresponding entanglement entropy has a divergent term and indeed for a
metric with Neumann boundary condition the resultant entanglement entropy is exactly the
same as that in the Einstein gravity. We will also make a comment on the fi rst law of the
entanglement thermodynamics for the conformal gravity in four dimensions.
