Douglas Walker (born 28 July 1973 in Inverness), also known as Doug or Dougie Walker, is a former Scottish sprinter. He represented Scotland at the Commonwealth Games in 1994 and 1998. He was a relay medallist at the 1997 World Championships in Athletics and at the 1998 European Athletics Championships he claimed a 200 metres/relay gold medal double.

Educated at George Heriot's School in Edinburgh, in 1998 he became European champion in both 200 metres and 4x100 metres relay. With 31.56 seconds he is the European record holder in 300 metres, although this distance is rarely run.

He tested positive for the anabolic steroid nandrolone in 1998 but was cleared of all charges by a UK Athletics disciplinary committee in 1999.^[1] IAAF later overturned that decision, applying their strict liability rule and he received a two-year ban in 2000. Despite an attempted comeback following his suspension, the ban effectively ended his elite level athletics career.^[2]
