The women's quadruple sculls event at the 2020 Summer Olympics took place from 23 to 28 July 2021 at the Sea Forest Waterway.

[2] This was the 12th appearance of the event, which has been held every year since women's rowing was introduced in 1976.

Each National Olympic Committee (NOC) has been limited to a single boat in the event since 1912.

There were 10 qualifying places in the women's quadruple sculls:[2] This rowing event was a quadruple scull event, meaning that each boat is propelled by four rowers.

The "scull" portion means that the rower uses two oars, one on each side of the boat; this contrasts with sweep rowing in which each rower has one oar and rows on only one side.
