Tillie Anderson (April 23, 1875 – 1965) was a road and track cyclist.
Anderson emigrated to the United States as a teenager in 1891 and found work as a seamstress. However, she quickly turned to the new sport of women's bicycling and was a champion cyclist in almost all forms of the sport, particularly the favoured six-day events of the era. At 18, The League of American Wheelmen named her the best female cyclist in the world, and she held the title of world champion until 1902, when women were banned from racing due to the perceived level of danger in the sport.
