We report near-infrared spectroscopy of the Galactic transient ASASSN21lk (AT2021quw; Kawash et al. TNS ID #114793) discovered by ASASSN (Shappee et al. 2014). On UT 2021-06-29, we obtained a near-infrared spectrum of the transient using the TripleSpec spectrograph on the Palomar 200-inch telescope. The reduced spectrum shows several broad emission lines of hydrogen, O I and C I. The hydrogen lines show a weak P-Cygni absorption component blueshifted by 1750 km/s. We measure a full-width-at-half-maximum of ~ 1800 km/s for the hydrogen lines. Overall, the spectrum is consistent with a Galactic classical nova.
