Grant Nelson (born 27 April 1971 in London), also known as Wishdokta, Bump & Flex and N'n'G, is an English DJ, remixer and record producer.

Nelson is heralded as one of the godfathers of UK garage due to his numerous club hits on his Nice 'n' Ripe record label in the early 1990s. It was his sound along with a few others that gave birth to the then known as 'Sunday Scene' which evolved into UK garage.
