We present a search for point sources of high energy neutrinos using 3.8 yr of data recorded by AMANDA-II during 2000–2006. After reconstructing muon tracks and applying selection criteria designed to optimally retain neutrino-induced events originating in the northern sky, we arrive at a sample of 6595 candidate events, predominantly from atmospheric neutrinos with primary energy 100 GeV to 8 TeV. Our search of this sample reveals no indications of a neutrino point source. We place the most stringent limits to date on E^-2 neutrino fluxes from points in the northern sky, with an average upper limit of E²Phi_nuµ+nutau<=5.2×10^-11 TeV cm^-2 s^-1 on the sum of nu_µ and nu_tau fluxes, assumed equal, over the energy range from 1.9 TeV to 2.5 PeV.
