Gargantuan is the debut studio album by U.K. electronic duo Spooky (Charlie May and Duncan Forbes), released by William Orbit's Guerilla Records in March 1993.

Today Gargantuan is regarded as a landmark album in the history of progressive house and British dance music. As Guerilla’s standard bearer, they helped coalesce an immersive sound that was neither Detroit, nor Chicago, nor Manchester.

The duo became renowned for being at the forefront of the progressive house scene that emerged in the aftermath of the "post-rave comedown", joining fellow acts like Orbital and Underworld in re-casting house music in an energetic live environment.

Gargantuan has been out of print on vinyl since 2006 and is re-released.
