Stephen Russell Leicht (born January 9, 1987) is an American professional stock car racing driver who last competed part-time in the ARCA Menards Series, driving the No. 31 Chevrolet for Rise Motorsports. He has previously competed in the NASCAR Cup Series (where he was the 2012 Rookie of the Year) NASCAR Xfinity Series and the NASCAR Truck Series. Leicht also has over 150 feature event wins in quarter midgets and go-kart racing.

When he was seven years old, Leicht began racing quarter midgets and began advancing into go-karts. At the age of eleven, Leicht was participating in the Go Kart Nationals, when he collided with the flag stand and was sent flying from his racecar. He suffered a burst spleen as a result of the accident, and was kept out of racing for six months.^{[citation needed]}

At the age of twelve, Leicht began racing stock cars and got his GED to focus full-time on racing, and was named Motorsports Magazines Rising Star of the Year in 2000. At the age of fifteen, he ran his first full year in the American Racing Association and was named Rookie of the Year.

In 2005, Leicht moved to Wisconsin to work with veteran American Speed Association crew chief Howie Lettow. Leicht collected five wins en route to winning the national championship in the American Speed Association Late Model series for WalTom Racing. He won both races that he attempted in the American StockCar League. He finished first or second in thirteen of sixteen events that entered between the two series. He started eighth in his Busch series debut at Memphis Motorsports Park, and finished thirteenth. He ran another race at Phoenix, starting seventeenth and finishing nineteenth.

In 2006, Leicht ran ARCA Re/Max Series events for Yates Racing and WalTom Racing. He earned his first career ARCA series win in his second career start at Nashville Superspeedway in April. He also made four Busch series starts in 2006, posting two top-ten qualifying efforts. On July 23, he made his first Nextel Cup Series start in the Pennsylvania 500 at Pocono Raceway for Yates Racing, qualifying 36th and finishing 33rd, one lap behind.

In 2007, Leicht ran the full NASCAR Busch Series schedule. He won his first race at Kentucky Speedway and finished seventh in the final drivers' points ranking. At the end of the season, Robert Yates Racing released Leicht from his contract because of sponsorship and finance issues. 2008 saw Leicht land a part-time stint in Richard Childress' No. 21 Nationwide car, sharing driving duties with Bobby Labonte. Leicht ran four races with a best finish of seventh at Phoenix International Raceway. However, after Talladega, a lack of sponsorship sidelined Leicht until Texas in the fall, where he finished eighteenth.

In 2009, Leicht drove the No. 29 Chevrolet Impala in thirteen races. Leicht was originally slated to run 23 events, but his races were nearly halved by the addition of Clint Bowyer as co-driver. He ran nine total races and had six top-ten finishes. He was released from RCR at the end of the year and signed to attempt 29 races for D'Hondt Humphrey Motorsports in the No. 91 car in 2010, but was released after two races.

Leicht competed in his first NASCAR race since 2009 (and his first Sprint Cup start since 2006) in Tommy Baldwin Racing's No. 36 Chevrolet in 2011, while regular driver Dave Blaney piloted the team's second car, the No. 35 Chevrolet. The move gave Leicht a guaranteed start while Blaney had to qualify on time. Blaney finished nineteenth while Leicht finished 24th despite running in the top-ten most of the race.
