Robert Rock (born 6 April 1977) is an English professional golfer. He was born in Armitage, near Lichfield in Staffordshire, and grew up and was educated in nearby Rugeley. He joined the European Tour as an affiliate member in 2003 and has remained a member ever since.

His breakthrough season was 2009, when he managed three second-place finishes, including at the Irish Open, where he tied for first place but lost to Irish amateur Shane Lowry in a three-hole playoff. He finished the 2009 season ranked in the top thirty of the Race to Dubai.

Rock won his maiden European Tour title at the BMW Italian Open in Turin in June 2011. He won by one stroke over Gary Boyd and Thorbjørn Olesen despite a final round 62 from Olesen. He made his U.S. Open debut the following week, having qualified via a European sectional qualifying event. Because of difficulties in obtaining a visa, he only arrived in the United States at 3:30am on the Thursday morning, less than 12 hours before the start of his round. Despite this, he managed an under-par opening round of 70 and finished tied for 23rd place at 3 under par.

Rock won his second European Tour title at the 2012 Abu Dhabi HSBC Golf Championship, finishing one shot ahead of Rory McIlroy. He entered the final round at 11 under par, tied for the lead with Tiger Woods, but outshone the American on Sunday to shoot a 2 under round of 70 to claim victory. He is one of a few professional golfers that does not wear a hat while he plays, despite the sponsorship income it can bring.
