T99 was a Belgian techno band, best known for their rave anthem, "Anasthasia", which reached #14 in the UK Singles Chart in May 1991.

T99 was initially Patrick de Meyer, who released three solo works under this pseudonym. However, he heard Olivier Abbeloos (also of Quadrophonia) working on the track "Anasthasia", and suggested that Abbeloos release it as T99.
