Rob Moroso (September 28, 1968 - September 30, 1990) was a NASCAR racing driver who was champion of the NASCAR Busch Series (now Nationwide Series) in 1989, was posthumously awarded the 1990 NASCAR Winston Cup (now Sprint Cup Series) Rookie of the Year award. He was killed in a traffic accident on roads near his hometown of Terrell, North Carolina.

Born in Madison, Connecticut, he was the son of Dick Moroso, founder of Moroso Performance, suppliers of aftermarket automotive parts, and former owner of Moroso Motorsports Park in Jupiter, Florida.

NASCAR Busch career
He made his debut in the Busch series at age 17, driving the #23 Old Milwaukee Chevrolet, and later the #15 for Rick Hendrick. He won his first race in 1988, when he was 19. He finished second in the final Busch series points in 1988. Moroso won a total of six races from 1988 to 1989, including 3 consecutive at Charlotte Motor Speedway, and was voted the most popular driver on the circuit.

In 1989 Moroso, was vying with veteran driver Tommy Houston for the championship in the final race of the year, at Martinsville Speedway. Houston's engine failed during the race, while Moroso finished third and won the title by 55 points from Houston. At the time Moroso was the youngest champion in the history of NASCAR.

NASCAR Cup career
Moroso made his debut in Winston Cup in 1988 at Charlotte with Peak Antifreeze sponsorship, finishing 14th in his debut. He would race one more time in 1988 and ran two races in 1989 as a warm up for the following season. Moroso declared he was running for Rookie of the Year in the 1990 season with sponsorship from Crown Petroleum, driving the #20 Oldsmobile for his father. The highlight of the season was a ninth place finish in the Pepsi Firecracker 400 at Daytona.

Death
On September 30, 1990, Moroso was killed in an automobile crash near Mooresville, North Carolina only hours after finishing 21st in the Holly Farms 400 at North Wilkesboro Speedway. Traveling at estimated 75 mph (121 km/h), Moroso lost control of his vehicle on a curve with a 35 mph (56 km/h) posted speed limit. The resulting collision killed both Moroso and Tammy Williams, the driver of the vehicle in the opposite lane. The curve in which Moroso was killed is now called Dead Mans Curve, by the townspeople of Mooresville, NC.

Investigations revealed that he had been driving under the influence of alcohol. His blood alcohol level was 0.22, over twice the then legal level of 0.10. He also had been convicted of speeding four times. Judges could have revoked his license at least twice but the charges were reduced.

Moroso earned enough points after completing just 25 of 29 races that he was posthumously awarded the Raybestos NASCAR Rookie of the Year Award in 1990.
