We present a feasible scheme for teleportation of four-qubit cluster-class state in cavity QED. Two Greenherg-Horne-Zeilinger (GHZ) pairs are chosen as the quantum channel. By using the atom-cavity field interaction in the dispersive regime and with the assistance of a strong classical field, we can prepare the entangled quantum channel, accomplish the joint three-qubit measurement and then teleport the cluster-class state from the sender (Alice) to the Receiver (Bob) successfully. It is noted that this scheme is insensitive to both the cavity decay and the thermal field.
