We analytically evaluate the entanglement spectra of the superconductivity states in graphene, primarily focusing on the s-wave and chiraldx2-y2+idxysuperconductivity states. We demonstrate that the topology of the entanglement Hamiltonian can differ from that of the subsystem Hamiltonian. In particular, the topological properties of the entanglement Hamiltonian of the chiraldx2-y2+idxysuperconductivity state obtained by tracing out one spin direction clearly differ from those of the time-reversal invariant Hamiltonian of noninteracting fermions on the honeycomb lattice.
