Single epoch K-band photometry of 32 RR Lyrae stars in the young galactic globular cluster IC 4499 is presented. The mean magnitudes have been estimated using the K-band template light-curves of Jones et al. ([CITE]). We derive an independent estimate of the distance and reddening for the cluster based on the new --[Fe/H] relation from Bono et al. ([CITE]) which has a zero-point in agreement with the canonical LMC distance of . For an assumed metallicity of we find (random and systematic errors respectively) and in good agreement with the findings of Walker & Nemec ([CITE]) based on optical data. The distance estimate is very robust to uncertainties in the reddening estimate but naturally depends directly on the adopted zero-point of the --[Fe/H] relation.
