Men's quadruple sculls competition at the 2008 Summer Olympics in Beijing was held from August 10 to 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 three boats in each heat advanced to the A/B semifinals, with all others going to the repechage.

The A final determined the medals, along with the rest of the places through 6th.
