  A parton-model description of high-energy hadronic interactions in the
presence of Lorentz violation is presented. This approach is used to study
lepton-hadron and hadron-hadron interactions at large momentum transfer. Cross
sections for deep inelastic scattering and the Drell-Yan process are calculated
at first order for minimal and nonminimal Lorentz violation. Estimated bounds
are placed using existing LHC and future US-based Electron-Ion Collider data.
