Hieroglyphics, also known as the Hieroglyphics Crew and Hiero, is an American underground hip hop collective based in Oakland, California. It was founded in the early 1990s by rapper Del the Funky 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.

Since their inception, Hieroglyphics have found a following largely through their live concerts, podcasts ("Hierocasts"), and promotion through their website.

The collective uses a three-eyed, straight-lipped face logo that figures prominently on their albums, website, stickers, and clothing.
