Abstract Multiphoton supercoherent states are defined as eigenstates of m-th power of supersymmetric annihilation operator, where m is a positive integer. In this paper, we study the entanglement of such states. To this purpose, we use concurrence as measure of entanglement. The results show that multiphoton supercoherent states are entangled for all values of m. Also, the entanglement does not depend on the coherency parameter for m = 1 . Moreover, the entanglement for other values of m ( m > 1 ) depends on the coherency parameters. In these cases, the entanglement for arbitrary m coincide with the entanglement of states with m = 1 for large values of coherency parameter.
