Boris Said III (born September 18, 1962 in New York City) is an American race car driver. His father, Bob Said, was a Formula One race driver and US Olympic bobsled driver in 1968 and 1972. His NASCAR career began in 1995 as a "road course ringer" primarily due to his extensive road-racing experience. He currently competes part-time in the Sprint Cup Series, driving the No. 32 Ford Fusion for Go FAS Racing.

Said's early interest was in motorcycle racing. In 1985 while attending the Detroit Grand Prix as a spectator he met SCCA Champion, Bob Sharp.

He began racing with the SCCA in 1987. Said was named SCCA rookie of the year in 1988. In 1991 he began driving for Baer Racing, later to become Baer Brake Systems. Upon Baer's withdrawal from the series to focus on the manufacture of brakes in 1992, Said got another big ride driving in the IMSA series in 1993 driving a BMW M3. He won the 1997 and 1998 24 Hours of Daytona and 1998 12 Hours of Sebring in IMSA. He also became the first American to win the 24 Hours Nürburgring in 2005 driving a BMW Motorsport-entered BMW M3 GTR with co-drivers Pedro Lamy, Duncan Huisman and Andy Priaulx.
