Gerald Nadeau (born September 9, 1969) is an American former stock car racer.
He competed in the NASCAR Winston Cup Series (now Monster Energy NASCAR Cup Series).
He started racing in karting before moving up to car racing, driving in the 12 Hours of Sebring, the European Formula Ford Festival, and the Barber Dodge Pro Series.
Nadeau arrived in NASCAR, the highest and most expensive level of stock car racing in the United States, with a limited budget.
He started racing part-time in NASCAR and finished sixth in the 1996 Formula Opel Euro Series.
He started full-time racing in 1998 and came third in that year's NASCAR Rookie of the Year award standings.
After Nadeau took his first Top Ten finish at Talladega Superspeedway in 1999, he won his first NASCAR sanctioned race in the Winston West Series (now K&N Pro Series West) at Las Vegas Motor Speedway.
He earned his first Winston Cup victory at Atlanta Motor Speedway the following year.
Nadeau achieved his top NASCAR season in 2001 when he finished seventeenth in points, but his racing career ended in 2003 after he suffered serious injuries in a practice crash.
He attempted a comeback before moving on to mentor drivers.
