We compute the on-shell wave function renormalization constant to four-loop order in QCD and present numerical results for all coefficients of the SU(N-c) color factors. We extract the four-loop Heavy Quark Effective Theory anomalous dimension of the heavy-quark field and also discuss the application of our result to QED.
