Zigaexperientia is the third studio album by the Japanese J-pop band Supercell, released on November 27, 2013 by SME. The album contains 15 music tracks written by Ryo, and sung by Koeda, though officially Koeda is not a member of Supercell. Six of the tracks were previously released on five of Supercell's singles. Three different editions of the album were released: a regular CD version, a CD+DVD limited edition, and a CD+BD limited edition. Zigaexperientia peaked at No. 7 on the Japanese Oricon weekly albums chart.

Seven of the songs were used as theme songs for various media: "My Dearest" and "Kokuhaku" were used as theme songs for the 2011 anime television series Guilty Crown; "Hakushukassai Utaawase" was used as the opening theme for the 2013 rebroadcast of the 2010 anime series Katanagatari; "Yeah Oh Ahhh Oh!" was used in a television commercial for the vocational school HAL; "Gin'iro Hikōsen" was the theme song to the 2012 anime film Nerawareta Gakuen; "The Bravery" was used as the second ending theme to the 2012 anime series Magi: The Labyrinth of Magic; and "Bokura no Ashiato" was used as the ending theme to the 2012 anime series Black Rock Shooter.

Between 2009 and 2011, Nagi Yanagi provided the vocals for Supercell's releases, ending with Supercell's second studio album Today Is A Beautiful Day (2011). Following this, Supercell held auditions from May 25 to June 19, 2011 for the vocalist on the band's third album. The main criteria for the vocalist was his or her voice, as Supercell was not concerned with the singer's gender or age. Out of about 2,000 candidates, then 15-year-old female singer Koeda was chosen. Ryo began by thinking about what kind of melody would fit Koeda's aggressive voice. He brought together various guitars and sound effectors and started composing music for the album once he found the desired timbre using drop D tuning, which also influenced the writing of the lyrics. Ryo was partially influenced by watching Pink Floyd's Live at Pompeii concert film and bought a vintage Marshall guitar amp after seeing it used in the film. Ryo also cited Muse as an influence, wanting to make music that makes people smile. According to Ryo, the album's title is a portmanteau of the Japanese word for ego, jiga (自我) (or ziga in kunrei or nihon romanization), and the Latin word for experience, .
