Gregory Alan Hancock (born June 3, 1970, in Whittier, California) is a former professional motorcycle speedway rider from the United States.

[4] Hancock first came to the United Kingdom at the end of the 1988 speedway season to ride exhibition races with fellow 18-year-old Californian Billy Hamill.

However, due to injury and problems with the American Motorcyclist Association, Hancock was not able to compete in the Individual World Championship until 1993.

The following year he joined with fellow American and Cradley teammate Billy Hamill to form Team Exide.

Hancock did not fare so well and finished the year in sixth place but won the World Team Cup with Hamill and Sam Ermolenko.

A 36-year-old Hancock finished the Grand Prix series in second place in 2006 and remained unbeaten in that year's World Cup but the USA did not qualify for the final as the rest of the team struggled.

He became the USA Speedway National Champion for the eighth time in 2009 and was subsequently named as the Racing Athlete of the Year by the American Motorcyclist Association (AMA).

Hancock clinched the 2014 World Championship during the Polish Grand Prix on October 11, 2014, and broke his own record of oldest title winner at 44 years and 130 days.

After having competed in every Speedway Grand Prix event since its inception in 1995, Greg Hancock missed his first SGP round in 2014 when he was forced to sit out the Nordic Grand Prix at Vojens with injury after his crash with Niels Kristian Iversen two weeks earlier.

After a one-year hiatus due to his wife suffering from breast cancer Hancock signed for clubs in Poland and Sweden and was given a 'permanent wild card' into the 2020 Grand Prix Series but after talking about his return with Hancock his son Wilbur said it would be difficult for Greg to return to speedway at the level he was racing when he took his break.

During the European speedway season he is based in Hallstavik, Sweden with his wife Jennie and three sons Wilbur, Bill, and Karl.
