Women's lightweight double 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 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.

The top two boats in each heat advanced to the A/B semifinals, with the rest going to the repechage.

The repechage heats gave rowers another chance at the top semifinals, as the best three boats in each of the two repechage heats also moved on to the A/B semifinals.

The C final gave the rest of the rankings, down to 17th place of the 17 boats competing.
