In this paper, we consider the uniqueness problems of finite‐order meromorphic solutions to Painlevé equation. Our result says that such solutions w are uniquely determined by their poles and the zeros of w − e j (counting multiplicities) for 2 finite complex numbers e 1 ≠ e 2 . As applications, we derive 2 uniqueness theorems about the Weierstrass ℘ function and Jacobi elliptic function s n , respectively.
