Ivan Gerald Mauger, OBE, (born 4 October 1939 in Christchurch, New Zealand) is a retired motorcycle speedway rider. He won a record six World Championships (Finals), a feat equalled only with the inclusion of the Speedway GP Championships by Tony Rickardsson of Sweden who won one World Final and five GP Championships. Mauger rode for several British teams – Wimbledon Dons, Newcastle Diamonds, Belle Vue Aces, Exeter Falcons, and the Hull Vikings.

In 1970, two men in the USA named George Wenn and Ray Bokelman said that if Ivan Mauger won his third World Final in a row at Wrocław (Poland), they would have the winning bike gold plated. Mauger duly won the World Final that year, and true to their promise, the bike was taken to America and Gold plated, and so was born the "Triple Crown Special".

Ivan Mauger's record is: World Champion: 1968, 1969, 1970, 1972, 1977, 1979 - R/Up 1971, 1973, 1974.
