Hieroglyphics, also known as the Hieroglyphics Crew and Hiero, are an American underground hip hop collective based in Oakland, California. The collective was founded in the early-1990s by rapper Del tha Funkee Homosapien. The collective is currently composed of rappers Del the Funky Homosapien, Casual, Pep Love, producer/manager Domino, DJ Toure, and the four individual members of the rap group Souls of Mischief: Phesto, A-Plus, Opio, and Tajai.

The Hieroglyphics combine fundamentally sound deliveries and lyrical content with original and sometimes jazzy or funky beats and samples. Since their inception, Hieroglyphics have found a following largely through their live concerts, podcasts ("Hierocasts"), and promotion through their website.
