Brett Moffitt (born August 7, 1992) is an American professional driver. He was a developmental driver for Michael Waltrip Racing until they shut down after 2015. He currently competes part-time in the NASCAR Camping World Truck Series, driving the No. 7 Toyota Tundra for Red Horse Racing. Moffitt is the 2015 NASCAR Sprint Cup Series Rookie of the Year.

Moffitt was born August 7, 1992 in Grimes, Iowa.

Moffitt began his racing career at the age of 10 in kart racing competition. In 2007, Moffitt won the Harris Clash in the IMCA Sport Modified division. Following several years of competition in karts and dirt track racing, Moffitt began competing on asphalt in 2008, driving in the American Speed Association's Late Model North Series. He made his debut in NASCAR touring series competition in 2009, driving in the K&N Pro Series East – then known as the Camping World East Series – for a team owned by Andy Santerre; winning the pole in his first race at Greenville-Pickens Speedway, he became the youngest driver ever to do so in the series. He went on to score two wins over the course of the season, finishing the year third in series points. His first win, in the fourth race of the season at South Boston Speedway in May, made Moffitt the youngest driver ever to win in the series, and the youngest to win in any NASCAR touring series; the mark stood until the following season, when it was eclipsed by Darrell Wallace Jr. in March 2010.

For the 2010 season, Moffitt moved to Joe Gibbs Racing; he scored two wins during the year on his way to finishing second in points at the end of the season. In 2011, he drove as a development driver for Michael Waltrip Racing, winning three times over the course of the K&N Pro Series East season and finishing third in the series standings.
