We report a search for a narrow t{bar t} resonance that decays into a lepton+jets final state based on an integrated luminosity of 5.3 fb{sup -1} of proton-antiproton collisions at {radical}s = 1.96 TeV collected by the D0 Collaboration at the Fermilab Tevatron Collider. We set upper limits on the production cross section of such a resonance multiplied by its branching fraction to t{bar t} which we compare to predictions for a leptophobic topcolor Z' boson. We exclude such a resonance at the 95% confidence level for masses below 835 GeV.
