We present recent results from the KEDR detector operating at the e+e- collider VEPP-4M in Novosibirsk. They include a high-precision measurement of the J/psi and psi(2S) masses, a study of the psi(2S) and psi(3770) parameters, a determination of the branching fraction B(J/psi -> eta_c gamma), a test of lepton universality in J/psi decays, a measurement of the leptonic width for the psi(2S) and a search for narrow resonances in the c.m. energy range 1.85 GeV - 3.10 GeV.
