James Murdock "Billy" Winn (August 27, 1909 – August 20, 1938) was an American racing driver.
Primarily a big car driver, Winn competed in four Indianapolis 500 races (1931, 1932, 1936, and 1937) and drove as a relief driver in 1933, 1934, 1935, and 1938.
He also drove his single-gear sprint car in the 1936 and 1937 Vanderbilt Cup races, running near the front of both races but being sidelined by mechanical failure both years.
Winn was killed in a non-points paying AAA Championship Car event held at the Illinois State Fairgrounds on August 20, 1938, when tire failure caused Winn's Miller to overturn on the fourth lap of the 100-mile race.
[1] Winn was inducted in the National Sprint Car Hall of Fame in 2003.
