Abstract: Precise measurements of electroweak parameters represent an important aspect of the LHC physics program. This paper discusses the measurement of the W boson mass, of the top quark mass, of the Z forward-backward asymmetry and of the production cross-section of boson pairs. The high center of mass energy of LHC and the large statistics samples of W, top, Z and diboson events that will be collected by the two general-purpose detectors ATLAS and CMS, will allow to improve the precision already achieved on the discussed parameters.
