Using cellular dynamical mean-field theory, we map out the antiferromagnetic (AF) phase of the two-dimensional Hubbard model as a function of interaction strength $U$, hole doping $\\delta$ and temperature $T$. The N\\'eel phase boundary is non-monotonic as a function of $U$ and $\\delta$. Frustration induced by second-neighbor hopping reduces N\\'eel order more effectively at small $U$.
