Roger De Coster (born August 28, 1944 in Uccle) is a Belgian motocross racer. His name is almost synonymous with the sport of motocross. He won five 500cc Motocross World Championships and tallied a record 36 500cc Grand Prix victories. He was known for his smooth, controlled riding style and a commitment to physical training. His training regime gave him the stamina that allowed him to circulate for most of the race in mid-pack before putting in a late charge through the field to victory when other racers had begun to tire. His stature is such in the world of motocross that he is often simply referred to as "The Man." He was also a Gold Medalist in the 1964 International Six Day Trial and won the 1964 Belgian Observed Trials National Championship.
