"Otome Sensō" (Z女戦争, "Girl's War") is the 8th single by the Japanese female idol group Momoiro Clover Z, released in Japan on June 27, 2012. It became the first Momoiro Clover's single to be certified Gold by the Recording Industry Association of Japan for shipments of 100,000 copies.

The single was released in four versions: Limited Edition A, Limited Edition B, Regular Edition 1, and Regular Edition 2 (Pokémon Edition). Each version has a different cover. The limited edition A came with a DVD featuring the music video for the title track, the limited edition B with the music video for the B-side "Push", but the limited editions contained less songs on the CD in comparison to the regular CD-only edition.

At over 7 minutes long in the music video version, the song is unusually long for a single. It was written by Etsuko Yakushimaru a.k.a. Tika α, who had composed for such artists as Tomohisa Yamashita and SMAP. When the title and the cover art were made public, she hinted at what the song was like by describing its outlook of the world as "When this battle is over, we are all going to a chorus contest." The song is a mosaic of Japanese-oldies-style melodies and contemporary music. The song can be interpreted as Momoiro Clover's (whose popularity is rising) proclamation of war for the top of the Japanese idol music scene, as a declaration of war for an ultimate idol showdown.

The B-side "Push" is a cheer anthem. It was used as an advertising song for an ice cream product called "Sō" by Lotte.

"Mite Mite Kotchitchi" is included on the regular editions only. It is an ending theme for the TV anime series Pokémon: Best Wishes! and for the Pokémon theatrical film Meloetta no Kirakira Recital.

There is a secret hidden on the cover of the Limited Edition B. If you look closely at Reni Takagi who is lying on the grass, there's an Sō ice cream treat nearby. On the edition's back cover, the girls form the ice cream's name, the character "爽" (Sō)
