We obtained an optical spectrum (range 370-845 nm) of SN 2016fbz(= Gaia16bbi),on UT Aug.27.6 2016 with the 2.16-m telescope (+BFOSC) at Xinglong Station of National Astronomical Observatories of China (NAOC). The spectrum is consistent with that of a type Ia supernovae at about one week after the maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) shows that it matches with SN 1989B at t = +8 days or SN 1992A at t = +7 days from the maximum light. After correcting for a redshift of 0.04 for its host galaxy, an expansion velocity of about 11500 km/s can be derived from the Si II 635.5 nm absorption.
