The 1966 Buddy Shuman 250 was a NASCAR Grand National Series event that was held on September 9, 1966, at Hickory Motor Speedway in Hickory, North Carolina. The transition to purpose-built racecars began in the early 1960s and occurred gradually over that decade. Changes made to the sport by the late 1960s brought an end to the "strictly stock" vehicles of the 1950s.
