Abstract. Let K be a locally compact hypergroup with left Haar measure and let P1 (K) = {f ∈ L1 (K) : f ≥ 0, kfk1 = 1 }. Then P1 (K) is a topological semigroup under the convolution product of L1 (K) induced in P1 (K). We say that K is P-amenable if there exists a left invariant mean on C(P1 (K)), the space of all bounded continuous functions on P1 (K). In this note, we consider the P- amenability of hypergroups. The P-amenability of hypergroup joins K = H ∨ J where H is a compact hypergroup and J is a discrete hypergroup with H∩J = {e} is characterized. It is also shown that Z-hypergroups are P-amenable if Z(K) ∩ G(K) is compact
