We report the spectroscopic classification of PSN J19590795-5555466 using a near-infrared spectrum (range 800-2400 nm) obtained with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas Observatory. The near-infrared spectrum of PSN J19590795-5555466 is most similar to that of Type Ib supernova SN 2008ax near maximum (Chornock, R. et al, 2011, ApJ, 739, 41) at an approximate redshift of 0.02. The faint host galaxy is anonymous, and its redshift is unknown. Several near-infrared He I P Cygni profiles are present at approximately 10000 km/s, assuming a redshift of 0.02.
