Giant resonances in 89Y were studied with inelastic scattering of 92. 5 MeV incident electrons at scattering angles of 75, 90, 105 and 120 degrees. In the excitation energy range of 6.1 to 38 MeV, nine transitions were observed. The previously reported E1 has been verified, but the broad E2 has been separated into two distinct resonances. Reduced transition probabilities and multipolarity assignments have been made. Resonances occurred at excitation energies of 6.69E2, 8.09E2, 10.01 E2, 11.21 E2, 12.46 E3, 13.63 M2 or E3, 14.86 E2, 16.60 E1, 27.85 E2.
