Ali Project (typeset as ALI PROJECT) is a Japanese rock band with a strong Japanese aristocrat-style image, consisting of Arika Takarano (宝野アリカ, Takarano Arika, vocals & lyrics) and Mikiya Katakura (片倉三起也, Katakura Mikiya, music & arrangement).

The band's work is divided into two styles, which lead singer/lyricist Arika Takarano has termed White Alice (白アリ, Shiro Ari) for the band's light, cheerful and/or refreshing songs, and Black Alice (黒アリ, Kuro Ari) for songs that take on a darker and more mysterious tone.

[1] Four years later in 1992 they changed their name and made their major debut with their single "Fall in love, maiden" (恋せよ乙女, Koi-seyo otome).

The band is notable in the anime community for having their songs featured in several anime productions, including Noir, Rozen Maiden, Kamichama Karin, .hack//Roots, Linebarrels of Iron, Code Geass, Phantom -Requiem for the Phantom-, Fate/Extra, Shigofumi, Another, Katanagatari, Rakudai Kishi no Cavalry, and Irina: The Vampire Cosmonaut.

Additionally, Mikiya Katakura has also provided the soundtrack to several anime series, such as Kaibutsu Oujo and Avenger.
