We consider the isospin-breaking corrections to charmless semileptonic decays of B mesons. Both the recently measured branching ratios of exclusive decays by the CLEO Collaboration and the end-point region of the inclusive lepton spectrum in form factor models can be affected by these corrections. Isospin corrections can affect the determination of {vert_bar}V{sub ub}{vert_bar} from exclusive semileptonic B decays at a level comparable to present statistical uncertainties. {copyright} {ital 1997} {ital The American Physical Society}
