In this paper, we generalise Nevanlinna's five-value theorem for derivatives of meromorphic functions by considering weaker assump-tions of sharing five values to partially sharing k(≥ 5) values. As a particular cases of our results, we deduce earlier results of C.-C. Yang [8, Theorem 3.2] and T.-G. Chen, K.-Y. Chen and Y.-L. Tsai [1].
