Gekijōban Meiji Tokyo Renka: Yumihari no Serenade (明治東亰恋伽～弦月の小夜曲～, Meiji Tokyo Renka the Movie: Serenade of the Crescent Moon) is a 2015 Japanese anime film directed by Hiroshi Watanabe and based on the visual novel Meiji Tokyo Renka by Mages. The film was released in nationwide Japanese theaters on July 18, 2015 in Japan.

The plot is centered on Mei Ayazuki, who is transported into the Meiji period and interacts with spirits and Japanese historical figures. The story is based on Kyōka Izumi's route, with the addition of Tōsuke Iwasaki, an original character, to introduce new elements to the plot. Despite failing to break in the top 15 on opening weekend, the film was praised for portraying the retro-styled elegance of the Meiji period as well as the relationship between Mei and Kyōka. The continuation of the story was featured in the sequel anime film, Gekijōban Meiji Tokyo Renka: Hana Kagami no Fantasia, which was released in theaters in 2016.
