The women's foil event at the 2020 Summer Olympics took place on 25 July 2021 at the Makuhari Messe.

[3] A National Olympic Committee (NOC) could enter up to 3 qualified fencers in the women's foil.

Finally, 4 spots are allocated by continental qualifying events: 1 from Europe, 1 from the Americas, 1 from Asia/Oceania, and 1 from Africa.

[2][4] The 1996 tournament had vastly simplified the competition format into a single-elimination bracket, with a bronze medal match.

The first session runs from 9 a.m. to approximately 4:20 p.m. (when the quarterfinals are expected to conclude), after which there is a break until 6 p.m. before the semifinals and medal bouts are held.
