This is a timeline of women in aviation which describes many of the firsts and achievements of women as pilots and other roles in aviation. Women who are part of this list have piloted vehicles, including hot-air balloons, gliders, airplanes, dirigibles and helicopters. Some women have been instrumental in support roles. Others have made a name for themselves as parachutists and other forms of flight-related activities. This list encompasses women's achievements from around the globe.

Women have been involved in aviation from the beginnings of both lighter-than air travel and as airplanes, helicopters and space travel were developed. Women pilots were also formerly called "aviatrices". Women have been flying powered aircraft since 1908; prior to 1970, however, most were restricted to working privately or in support roles in the aviation industry. Aviation also allowed women to "travel alone on unprecedented journeys". Women who have been successful in various aviation fields have served as mentors to younger women, helping them along in their careers.
