In this paper, we establish a variational principle for topological pressure on compact subsets in the context of amenable group actions. To be precise, for a countable amenable group action on a compact metric space, say \begin{document}$ G\curvearrowright X $\end{document} , for any potential \begin{document}$ f\in C(X) $\end{document} , we define and study topological pressure on an arbitrary subset and measure theoretic pressure for any Borel probability measure on \begin{document}$ X $\end{document} (not necessarily invariant); moreover, we prove a variational principle for this topological pressure on a given nonempty compact subset \begin{document}$ K\subseteq X $\end{document} .
