Harriet Quimby (May 11, 1875 – July 1, 1912) was an American pioneering aviator, journalist, and film screenwriter.

In 1911, she was awarded a U.S. pilot's certificate by the Aero Club of America, becoming the first woman to gain a pilot's license in the United States. In 1912, she became the first woman to fly across the English Channel. Although Quimby lived only to the age of 37, she influenced the role of women in aviation.
