We report the first quiescent detection of KV UMa, the optical counterpart of XTE J1118 + 480, in the near‐infrared. The observed magnitudes and colours are consistent with a K7–M0 V star, at the distance of 1.4 ± 0.2 kpc . The light curve shows strong orbital modulation with possible contamination from a superhump detected in the quiescent optical light curves.
