We report on near IR (J and K bands) observations of an region centered on the poorly studied open cluster King 5, for which only optical photometry existed. Photometry of two nearby fields is also reported. We found that the cluster is of moderate age (1.0 Gyr old), intermediate in age between the Hyades and NGC 752. Combining optical and IR photometry we obtain estimates for the cluster parameters. The color excesses , and are 0.50, 1.10 and 2.45, respectively. The true distance modulus turns out to be . As a consequence, King 5 is 1.9 kpc far from the Sun.
