4hero (sometimes referred to as 4 Hero or 4-Hero) are an electronic music group from Dollis Hill, London, comprising producers Mark "Marc Mac" Clair & Denis "Dego" McFarlane.

Marc Mac and Gus Lawrence set up Reinforced Records in 1989 to release their own productions as 4hero, with the group being completed by Dego and Ian Bardouille.

The follow-up EP, Combat Dancin', underpinned the sub-bass pressure of the bleep 'n' bass artists associated with Sheffield's Warp Records, such as LFO and Nightmares on Wax, with mid-tempo hip-hop-style breakbeats.

In late 1992 and early 1993, 4hero would release the darkcore Journey from the Light EP, which according to and referenced by music journalist Simon Reynolds, "If anyone can claim to have invented dark-core, it's 4 Hero".

The album gained critical acclaim and a place on the shortlist for 1998's Mercury Music Prize as well as picking up a MOBO award in the same year.

4hero's fourth album, Creating Patterns (2001), featured another Ursula Rucker collaboration, an appearance from Jill Scott, and a cover of Minnie Riperton's classic 1970s song "Les Fleurs" with Carina Andersson as the lead vocalist.

Comparisons have been drawn between them and East London band Shut Up and Dance, with both bands evolving in the early 1990s as a rapprochement between the breakbeat-driven African-diasporic musical structures of hip-hop and reggae, and the dark, European reconstruction of the techno sound popularised by the likes of Joey Beltram, CJ Bolland and Mundo Muzique.
