We compute the mass of the charm quark using both quenched and dynamicallattice QCD calculations. We examine the effects of mass dependent latticeartifacts by comparing two different formalisms for the heavy quarks. We takethe continuum limit of the charm mass in quenched QCD by extrapolating fromthree different lattice spacings. At a fixed lattice spacing, the mass of thecharm quark is compared between quenched QCD and dynamical QCD with a sea quarkmass around strange. In the continuum limit of quenched QCD, we findm_c(m_c)=1.29(7)(13) GeV. No evidence was seen for unquenching.Comment: Added NP analysis of quenched data, corrected error in PCAC RGI mass,  updated strange quark mass discussion and references, unified notation and  corrected typos. No change in final result. Version accepted for publication  in JHE
