We present an overview of the muon reconstruction and identification methods employed by the D0 collaboration to analyze the Run II (2001-2011) data of the Fermilab Tevatron collider at . We discuss the performance of these methods, how it is measured using D0 data, and how it is properly modeled by the D0 simulation program. In its pseudorapidity acceptance, , the muon system identifies high-m>pm>_m>Tm> muons () with efficiencies ranging from 72% to 89%. Muons tracks are reconstructed in the D0 central tracking system with efficiencies ranging from 85% to 92% and with a typical relative momentum resolution of 10% for . Isolation criteria reject multijet background with efficiencies of 87-99%.
