We study the effects of virtual leptoquarks on charged current and neutral current processes at the ep collider HERA. We present the areas of parameter space that can be excluded at HERA by searching for deviations from Standard Model expectations. The best results are obtained by examining the ratio of neutral current to charged current cross sections, R=σNC/σNC, where, with 200 pb-1 of integrated luminosity for unpolarized e- and e+ beams, HERA can search for leptoquarks with masses up to ∼800 GeV, with leptoquark coupling strengths of order αem.
