Idol × Warrior Miracle Tunes! (アイドル×戦士 ミラクルちゅーんず!, Aidoru Senshi Mirakuru Chūnzu!) is a Japanese television series that aired from April 2, 2017, to March 25, 2018, on TV Tokyo. The show is the first installment of the Girls × Heroine Series conceived by Takara Tomy and OLM, Inc. with the assistance of Shogakukan and EXPG Studio, aimed towards a female demographic between ages 2 to 6. The general director of the series is Takashi Miike, supported by a staff full of newcomer screenwriters and directors. The series stars Asaka Uchida, Suzuka Adachi, Yuzuha Oda, Rina Usukura, and Mio Nishiyama. The plot is centered on Japanese idol girl group Miracle² (pronounced "miracle miracle"), elementary and middle school girls who transform into Idol Warriors to retrieve the Sound Jewels, artifacts from the Music Kingdom, to stop the Demon King from taking over the world.

Auditions were held in December 2015, and the cast was announced at Ciao Summer Festival in August 2016. Filming took place from September 2016 to July 2017, combining elements of dance, song, and drama, with assistance from dance and vocal teachers at EXPG Studios and emphasis on cuteness and natural femininity. In addition, the show utilizes special effects for the transformation and battle scenes, which were later added after principal photography. The show also launched a brief singing career for the main cast, with Miracle² holding music activities in real life to promote the show.

Despite low television ratings, the show was a success for its primary demographic and was credited as the start of a "new genre" aimed towards elementary school girls, especially because of Miracle²'s music activities and the show's toy line. The series achieved a wide demographic appeal to girls, due to it being a live-action show centered on female interests, and with parents, who enjoyed the dancing and music. Two manga adaptations and a video game were released. Along with several dubs in Thailand, South Korea, and China, the show also received an Italian remake in 2018. Following the show's end in 2018, it was succeeded by Magical × Heroine Magimajo Pures!
