Sub Sub were an English dance act from Handforth, Cheshire composed of Jimi Goodwin and twin brothers Andy and Jez Williams.

The threesome met at school in 1985 and became regulars at The Haçienda while composing their own material together. They had an underground 12" single ("Space Face" in 1991) and moderate commercial success in the early 1990s on Rob Gretton's label Rob's Records, including the single "Ain't No Love (Ain't No Use)" (featuring guest vocalist Melanie Williams) which reached #3 on the UK Singles Chart. The trio's only full-length album Full Fathom Five was released in September 1994.
