This thesis is a description of the measurement of the W boson mass using the D0 Run II detector with 770 pb^-1 of proton-antiproton collision data. These collisions were produced by the Tevatron at sqrt(s) = 1.96 TeV between 2002 and 2006. We use a sample of W -> e nu and Z-> e e decays to determine the W boson mass with the transverse momentum distribution of the electron and the transverse mass distribution of the boson. We measure M_W = 80340 +- 37 (stat.) +- 26 (sys. theo.) +- 51 (sys. exp.) MeV = 80340 +- 68 MeV with the transverse momentum distribution of the electron and M_W = 80361 +- 28 (stat.) +- 17 (sys. theo.) +- 51 (sys. exp.) MeV = 80361 +- 61 MeV with the transverse mass distribution.
