"Anniversary!!" is a song recorded and performed by Japanese collective unit E-girls. It first appeared on their greatest hits album E.G. Smile: E-girls Best (2015), and subsequently served as the single of their fourth studio record E.G. Crazy (2017). The track was released on May 20, 2015 through Rhythm Zone and Avex Music Creative Inc. in three physical formats—two CD's and a DVD bundle—and for digital consumption. The song was written by Hana Utsugi, composed by Sky Beatz, Fast Lane and Lisa Desmond, and produced by Exile's Hiro. "Anniversary!!" is their first single released in 2015 to only feature selective members in the line-up.

Musically, "Anniversary!!" is a J-pop number that incorporates elements of dance rock. Described by their management as a pop entry for the summer season, the physical and digital packaging included the track "Saturday Night (Rock na Yoru ni Mahou wo Kakete)", which is a cover song originally performed by Scottish band Bay City Rollers, similarly sharing the same song title. Vocally, the single features the singing of Shizuka, Ami, Karen Fujii and Reina Washio.

Upon its release, "Anniversary!!" received positive reviews from music critics, who commended the composition and felt it was a suitable tune for the summer season. Commercially, it experienced success in Japan, peaking at number three on the Oricon Singles Chart and Japan Hot 100, the latter published by Billboard. It was certified gold by the Recording Industry Association of Japan (RIAJ) for digital sales of 100,000 copies. In order to promote the single, E-girls performed in the accompanying music video, which was directed by Yu-ya Hara, depicting the girls dancing and camping in California. Additionally, the girls sung and performed the track on several concert and shows.
