We report that a CCD spectrum (range 350-1050 nm) of AT2016fij was obtained on Aug. 27.5 UT with the 3-m Shane reflector (+Kast) at Lick Observatory. We classified the event via cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin & Tonry 2007, Ap.J. 666, 1024) including the updated templates of Silverman et al. (2012, MNRAS, 425, 1789) and Liu & Modjaz (2014, arXiv:1405.1437). The spectrum shows AT2016fij to be a normal Type Ia supernova within a few days of peak brightness (at the time of observation). SNID identifies spectroscopic similarities to SNe 1994ae, 2006dw, and 1994D, and after correcting for the host galaxy's redshift of z = 0.0389 (2dFGRS S501Z101; NED) the Si II 635.5 nm absorption minimum indicates an expansion velocity of about 11,000 km/s.
