Speedy J (born Jochem George Paap in 1969, Rotterdam), is a Dutch electronic music producer based in the city of Rotterdam. His breakthrough came with the release in 1992 of the minimal techno track Pullover. Subsequently his material became more mellow as he moved away from the hardcore sounds that were then becoming popular in Belgium and the Netherlands.

His debut album Ginger (1993) was released on Richie Hawtin's Plus 8 record label in Canada, while in the UK it was part of Warp Records' Artificial Intelligence series of electronic listening music. A further, more introspective release, G-Spot followed in 1995; a live album, !ive, was also released. Afterwards his work, which included Public Energy No.1 (1997) and A Shocking Hobby (2000) became more experimental, importantly influencing the development of what is known as "IDM", or intelligent dance music.
