Tajai Massey, known by the stage name, Tajai (born: April 21, 1975), is an American rapper and producer. He is one of the four founding members of Oakland, California-based underground hip hop group Souls of Mischief, and, with the Souls of Mischief, a part of the eight-person, alternative hip hop collective, the Hieroglyphics.

Born in Stanford, California, Tajai moved with his family across the San Francisco Bay to Oakland, California when he was 2 years old. In elementary school, Tajai met fellow Souls of Mischief member A-Plus, and the duo began their nascent rap careers. Tajai eventually introduced A-Plus to future Souls of Mischief members Phesto and Opio, and the group formed in high school before releasing their debut album, 93 'til Infinity on Jive Records in 1993. He graduated from Stanford University in 1997 with a degree in anthropology.

After Tajai and the Souls of Mischief were dropped by Jive, the group was incorporated into the Hieroglyphics in 1995, at the urging of Del tha Funkee Homosapien.

Tajai has contributed to all four Souls of Mischief albums, as well as the two Hieroglyphic studio albums. He has also produced or performed on solo projects of various Hieroglyphics' members.

In 1999, Tajai and the Hieroglyphics' then-webmaster, StinkE, formed the conceptual group SUPREMEeX, which released an enhanced CD, Projecto: 2501, and in 2005, released the album Nuntype.

Tajai is also a member of Crudo, a new project featuring Mike Patton and Dan the Automator, who made their live debut in 2008.
