Let Ω be a finitely connected domain. We prove constructively the existence of a universal Laurent series, that is, a holomorphic function f on Ω having universal approximation properties connected with partial sums of Taylor and Laurent expansions.

Keywords: Universal functions, universal Laurent series.
