Lake Chambers Speed (born on January 17, 1948) is a former NASCAR driver.

Lake was named after the best friend of his father, Bob Lake. Lake's father Leland L. Speed took office as the Mayor of Jackson, Mississippi in 1948, the same year that he was born. He started his racing career at the age of thirteen racing karts, much to the displeasure of his family. Over the years, Speed won the International Karting Federation (IKF) National Championship six times and in 1978 he won the prestigious Karting World Championship over among others, future Formula One legend and icon Ayrton Senna. As of 2010, Speed is the only American to win the championship.

In 1980 after considering racing in other series such as Formula One, CART, and IMSA, and getting advice from current Lowe's Motor Speedway promoter, Humpy Wheeler, Speed chose to go NASCAR racing. According to Speed, "It was the highest mountain to climb." Speed's relative unfamiliarity with the NASCAR scene led him to buy his first car from someone in Chicago. Speed started nineteen races in his rookie year scoring an eighth at Darlington Speedway in his third career start. Speed also scored finishes of seventh at the spring Talladega Superspeedway race, eighth at Talladega's fall event, seventh at Charlotte's fall event and eighth at the season ending race at Ontario Motor Speedway. Speed finished twenty-second in overall points and second to Jody Ridley in the rookie of the year standings.
