description The design of the CMS muon identification and reconstruction is presented, as well as its performance on cosmic rays and collision data. Efficiencies of various high-level trigger, identification, and reconstruction algorithms have been measured for a broad range of muon momenta, and were found to be in good agreement with expectations from Monte Carlo simulation. Using the cosmic ray data, CMS has measured the charge asymmetry of cosmic muons, as a function of the muon momentum. The excellent performance of the detector allowed detection of muons in the momentum range from 3 GeV/c to 1 TeV/c. For muon momenta below 100 GeV/c the flux ratio is measured to be a constant 1.2766 +- 0.0032(stat) +- 0.0032(syst), the most precise measurement to date.
