We present a measurement of the W boson mass using data corresponding to 4:3 fb-1 of integrated luminosity collected with the D0 detector during Run II at the Fermilab Tevatron pp collider. With a sample of 1 677 394 W → ev candidate events, we measure MW = 80:367 ± 0:026 GeV. This result is combined with an earlier D0 result determined using an independent Run II data sample, corresponding to 1 fb-1 of integrated luminosity, to yield MW = 80:375 ± 0:023 GeV.
