We examine the gauge dependence of lower bounds on the Higgs boson mass obtained from the requirement that the electroweak vacuum be the global minimum of the effective potential. We study a simple model, the spontaneously broken Abelian Higgs model coupled to a chiral quark doublet in a two-parameter R{sub {xi},u} gauge, and demonstrate that the lower bounds on the Higgs boson mass obtained in this model are dependent on the choice of gauge parameters. We discuss the significance of this result for calculations in the standard model. {copyright} {ital 1997} {ital The American Physical Society}
