The Mu2e experiment in Fermilab will search for the charged-lepton flavor violating (CLFV) coherent neutrinoless conversion of a muon into an electron in the field of an aluminum nucleus, a key process in the search for physics beyond the Standard Model. This measurement will improve sensitivity by 4 orders of magnitude over existing limits, presenting a rare opportunity for an indirect probe of new physics beyond the reach of current or planned high energy colliders. To achieve a single conversion event sensitivity better than 3e-17 the experiment requires a very intense muon beam and a high precision measurement of the ~105 MeV/c conversion electron momentum, while reducing to negligible all background contributions in the signal window. The measurement strategy, the detector design, and the current experimental status will be presented in this talk.
