We extend the conventional mode-coupling theory of supercooled liquids to systems under stationary shear flow. Starting from generalized fluctuating hydrodynamics, a nonlinear equation for the intermediate scattering function is constructed. We evaluate the solution numerically for a model of a two-dimensional colloidal suspension and find that the structural relaxation time decreases as \stackrel\ifmmode \else \.\fi\ensuremathγ^\ensuremath-\ensuremathν with an exponent \ensuremathν<~1, where \stackrel\ifmmode \else \.\fi\ensuremathγ is the shear rate. The results are in qualitative agreement with recent molecular dynamics simulations. We discuss the physical implications of the results.
