Russell Colin Knox (born 21 June 1985) is a Scottish professional golfer who plays on the PGA Tour.

Knox joined the European Tour at the start of 2016 but just failed to gain an automatic place on the 2016 Ryder Cup team and was not chosen as one of the captain's picks.

His first PGA Tour event as a full member was the 2012 Sony Open in Hawaii where he missed the cut by a single stroke.

He made only 12 cuts in 23 events in 2012 and finished 143rd on the money list to remain conditionally exempt on the PGA Tour for 2013.

Knox had a good start to the 2015 PGA Tour season with a third place in the Shriners Hospitals for Children Open in late 2014.

Knox also made a rare appear in Europe at the 2015 Aberdeen Asset Management Scottish Open, finishing in a tie for 10th place.

The week after his WGC success, Knox lost in a three-way playoff in the OHL Classic at Mayakoba, Graeme McDowell making a birdie at the first extra hole.

Knox became a European Tour member at the start of the 2016 season in the hope of playing for Europe in the 2016 Ryder Cup.
