Abstract submitted to the International Europhysics Conference on High Energy Physics July 12 - 18, 2001, Budapest, Hungary _________________________________________________________________________ Search for leptoquarks in ep collisions at HERA ZEUS Collaboration Abstract A search for leptoquark production has been performed in neutral and charged current deep inelastic scattering events, e^+p -> e^+X and e^-p -> nu X, with the ZEUS detector at HERA using 115 and 16 pb^{-1}, respectively. No signal was observed. Limits on the Yukawa coupling, lambda, have been set as a function of the leptoquark mass.
