The goal of the Daya Bay reactor neutrino experiment is to measure $\theta_{13}$ with a sensitivity in $\sin^{2}(2\theta_{13})$ of 0.01. To achieve this, the cosmic ray induced backgrounds must be reduced to a low level. Daya Bay's muon veto system will consist of a 2.5 m active water shield and RPCs. The muon tagging efficiency of the combined system is expected to be greater than 99.5%. The details of the muon system and estimates of the expected backgrounds will be described.
