James Ross Donaldson (born 19 October 1975) is a Welsh professional golfer who plays on the European Tour. He turned professional in 2000. Having failed to come through the European Tour's qualifying school, in 2001 he played predominantly on the second tier Challenge Tour. He won the BMW Russian Open and the Telia Grand Prix in Sweden on his way to second place in the Challenge Tour Rankings.
Donaldson played well enough on the 2014 PGA Tour as a non-member to earn a PGA Tour card for the 2014–15 season.
