In this paper, we consider the three-dimensional non-autonomous micropolar equations with damping term in periodic domain ${\mathbb{T}}^3$. By assuming external forces satisfy certain condtions, the existence of pullback $\mathcal{D}$-attractors for the three-dimensional non-autonomous micropolar equations with damping term is proved in $V_1\times V_2$ and $H^2\times H^2$ with $3<\beta <5$.
