Quantum-chromodynamic corrections to the transverse-momentum distribution of dileptons are determined. For p+p ..-->.. l/sup +/l/sup -/+X the dominant Born term is known to be provided by the subprocess q+g ..-->.. q+..gamma..*; the corrections are due to q+q ..-->.. q+q+..gamma..*. At large transverse momenta these corrections are found to be significant, and improve agreement with experiment. As a by-product, factorization of mass singularities and the implementation of scale violations in the gluon distribution are explicitly shown.
