These are the official results of the Women's 3.000 metres event at the 1991 IAAF World Championships in Tokyo, Japan. There were a total number of 40 participating athletes, with three qualifying heats and the final held on Monday 26 August 1991.
The winning margin was 0.24 seconds which as of 2024 remains the narrowest winning margin in the women's 3,000 metres at these championships. Given that this event was discontinued after the 1993 edition, it is unlikely to be reduced.
