Donald R. Pierce (born April 13, 1937) is a retired U.S. Racing Hall of Fame jockey in thoroughbred horse racing. Based in California, Pierce earned his first win in 1954 and went on to become a leading jockey in the 1960s and 1970s. In 1967, he was voted the George Woolf Memorial Jockey Award which honors a rider whose career and personal conduct exemplifies the very best example of participants in the sport of thoroughbred racing. Of this recognition by his peers, Pierce said "I've got the trophy sitting on my mantle and it's very important to me. Without a doubt, it ranks close to anything I ever achieved in racing. It's very, very special."
