Florence Madeline "Madge" Syers (née Cave, 16 September 1881 – 9 September 1917) was a British figure skater. She became the first woman to compete at the World Figure Skating Championships in 1902 by entering what was previously an all-male event and won the silver medal, which prompted the International Skating Union (ISU) to create a separate ladies' championship. Syers was the winner of the first two ladies' events in 1906 and 1907, and went on to become the Olympic champion at the 1908 Summer Olympics, the first Olympic Games to include figure skating. She also competed as a pairs skater with her husband Edgar Syers, winning the bronze medal at the 1908 Olympics.

Florence Madeline Cave was born on 16 September 1881 in Kensington, London, one of 15 children of Edward Jarvis Cave, a builder, and his wife Elizabeth Ann. She was a proficient figure skater, as well as a gifted swimmer and equestrienne. Madge became a regular at the Prince's Skating Club in Knightsbridge, which had been formed in 1896 and was popular with aristocratic society in London.
