Dimension 5 is a British Goa trance project. Dimension 5 was one of the first Goa trance groups and released vinyl and CDs. The group started in 1989, and around 1994 they released their first early Goa trance recordings, which they described as "space techno". Back then the group existed of four members: Charlie Clarke, Graham Franklin, Kerry Palmer and Nick Wenham. They started their own label, Intastella Records, in 1996 to have total musical freedom.

This resulted in the making of their first full album, Transdimensional in 1997. The album was in demand but never widely distributed. The project's music was not just released on Intastella Records. Many of their tunes made between 1995 and 1998 were also featured on compilations of other labels (Transient Records, Psychic Deli, Leguan, Phantasm Records, BNE and others).

In 1998, the group got an extra member, Christer Børge Lunde (also known as Ra, Electron Wave and Outzider). This resulted in another album Second Phaze (2000), released by Blue Moon in Thailand. The CD was re-released by the German labels Velvet Inc/Nova Tekk. After this album, Dimension 5 stopped making music.
