Rumic Theater (高橋留美子劇場, Takahashi Rumiko Gekijō), or Rumiko Takahashi Anthology (高橋留美子傑作集, Takahashi Rumiko Kessakushū), is a Japanese manga series composed of short stories written and illustrated by Rumiko Takahashi. New stories are published annually in Shogakukan's Big Comic Original magazine (and other Shogakukan magazines), and have been since 1987.

A 13-episode anime adaptation of these short stories was produced by TMS Entertainment and broadcast on TV Tokyo from July to September 2003, followed by the sequel series Rumic Theater: Mermaid Forest, adapting Takahashi's Mermaid Saga. A two-episode Japanese television drama based on the stories was broadcast on NHK-BS Premium in July 2012.
