Simon Dyson (born 21 December 1977) is an English professional golfer who is currently a member of the European Tour, having formerly played on the Asian Tour.
Dyson was born in York, England. In 1999, he was runner-up in the English Amateur and won the Finnish Amateur title. He was also a member of the Great Britain & Ireland Walker Cup team that year, before turning professional in September.
In 2000, Dyson topped the Asian Tour Order of Merit after winning three tournaments on that tour, and was also Rookie of the Year. He also played a small number of events on the European Tour in 2000. Since 2001 he has played mainly on the European Tour, and has finished in the top 100 on the Order of Merit nine times, the only exception being in 2003. In March 2006 he won his maiden European Tour title at the Enjoy Jakarta Indonesia Open and he followed up later that year by winning the KLM Open in a play-off over Richard Green. These victories helped him to finish a career-high, at the time, 21st place on the Order of Merit and climb into the top 100 of the Official World Golf Rankings for the first time in his career.
