Robert Rock (born 6 April 1977) is an English professional golfer. He was born in Armitage, near Lichfield in Staffordshire. He grew up and was educated in 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.
