We prove some uniqueness theorems for meromorphic functions and their derivatives that share a meromorphic function whose order is less than those of the above meromorphic functions. The results in this paper improve those given by G. G. Gundersen L. Z. Yang, J. P. Wang, J. M. Chang Y. Z. Zhu, and others. Some examples are provided to show that our results are the best possible.
