Women's quadruple sculls competition at the 2008 Summer Olympics in Beijing was held between August 10 and 17, at the Shunyi Olympic Rowing-Canoeing Park.

The "scull" portion means that each 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.

The top boat in each heat advanced to the A final, while all others went to the repechage.

The B final gave rankings to the two remaining crews, giving them places of 7th and 8th.
