William "Willie" Knapp (August 21, 1888 – October 26, 1972) was an American thoroughbred horse racing Hall of Fame jockey. He was known for racing horses such as Exterminator and Sun Briar. He became the jockey for Exterminator in the 1918 Kentucky Derby. He was expecting to race Sun Briar, an extremely fast colt, but Sun Briar became ill and he had no choice but to race Exterminator, Sun Briar's training horse. However, Exterminator won the Derby, and Knapp became his lifelong jockey.
