John Dowd, also known as "The Junk Yard Dog", (born August 10, 1965) is an American former professional motocross racer.
Dowd progressed quickly in the sport and was soon beating riders with many years more experience of motocross than himself and was able to turn professional by age 21.
With his relatively late start, Dowd has achieved the best results of his career later in life, which is unusual compared to his typical competitors.
His greatest strengths were his stamina and endurance, enabling him to ride hard for the entire moto.
He finished on the podium in 3rd place at the 2005 Southwick 250cc National just shy of his 40th birthday, aboard a privateer Suzuki RMZ450.
