Cook Neilson (born August 24, 1943) is an American former journalist and motorcycle racer known widely for his win on a Ducati 750SS at the Daytona International Speedway in 1977. He graduated from Princeton in the mid-1960s, was hired as associate editor of Cycle in September 1967; promoted to editor in 1969, and is credited for making that magazine successful through the 1970s. While at Cycle magazine, he wrote a series of articles on the cookbook construction of a 160 mph (260 km/h) Top Fuel Harley-Davidson Sportster.
Neilson wrote briefly also at Car and Driver in the late 1960s, notably excoriating the 1968 Kadett LS 1.5L wagon in what has been described as an automotive assassination review, sacrificing the car in order to increase the magazine's prominence.
