We present a measurement of the W boson mass using data collected by the D0 experiment at the Fermilab Tevatron during 1994--1995. We identify W bosons by their decays to e\ensuremathν final states. We extract the W mass MW by fitting the transverse mass and transverse electron momentum spectra from a sample of 28 323 \stackrel\ensuremath→We\ensuremathν decay candidates. We use a sample of 3563 dielectron events, mostly due to \stackrel\ensuremath→Zee decays, to constrain our model of the detector response. From the transverse mass fit we measure MW=80.44\ifmmode±\else\textpm\fi0.10(stat)\ifmmode±\else\textpm\fi0.07(syst) GeV. Combining this with our previously published result from data taken in 1992--1993, we obtain MW=80.43\ifmmode±\else\textpm\fi0.11GeV.
