Gravediggaz is an American hip hop group from New York City, known for its dark sense of humor and abrasive, menacing soundscapes. The group was formed in 1991, bringing together Prince Paul (The Undertaker), Frukwan (The Gatekeeper), Poetic (The Grym Reaper) and RZA (The RZArector). It came about largely due to the efforts of Prince Paul. The group pioneered the small hip-hop subgenre of horrorcore.
