Gary Mawson (born May 17, 1963) is a Canadian professional darts player who competes in the Professional Darts Corporation and British Darts Organisation events.
He currently resides in Pompano Beach, Florida, United States.
Mawson played darts for the USA in 2004 and the years immediately following, having previously played darts for Canada up to 2001.
Mawson used the nickname The Mauler for his matches.
Mawson's parents were born in Britain, and he also lived in Bolton, England for 4 years between the ages of 3–7 before moving back to Canada.
As a result, Mawson holds dual Canadian and British citizenship.
Despite living in the United States for many years, Mawson is yet to become a US citizen.
In more recent times, Mawson has been representing Canada again, such as at the televised 2019 US Darts Masters.
Mawson's biggest career achievement in darts was in reaching the final of the 2008 UK Open in Bolton, after upsetting the odds and defeating the 2-time defending UK Open champion, Raymond van Barneveld, 10–8 in the semi finals.
Van Barneveld had never previously lost at the UK Open and had won 16 matches in a row at the event.
