Oliver James Fisher (born 13 September 1988) is an English professional golfer.
Fisher was born in Chingford, London. He was a winner of the Faldo Series, Nick Faldo's development programme for young golfers, in 2003, 2004 and 2005 and as such was regarded as one of the best prospects of his generation. In 2005 he became the youngest player to take part in the Walker Cup.
In late 2006, while still an amateur, Fisher entered the European Tour's qualifying school. He finished fifth to become the youngest Briton to win a tour card and immediately turned professional. He made the cut at his first five European Tour events and ended the season just outside the top 100 on the 2007 Order of Merit to retain his card for 2008. A solid 2008 season which included a runner-up finish at the MAPFRE Open de Andalucía by Valle Romano, where he lost out in a playoff with Thomas Levet, saw him finish in 51st place on the Order of Merit.
