The 2003 Winn-Dixie 250 was a Busch Series event held at Daytona International Speedway on July 4, 2003. Dale Earnhardt, Jr dominated the event, leading stripe-to-stripe with the aid of teammate Michael Waltrip. A sixth place effort by Scott Riggs got him back on top of the points lead, sweating a two-point margin on David Green (20th).
