Abstract: CCD observations of the open cluster King 7 and two nearby fields have been made in the UBVRI passbands down to V ~ 20.0 mag. From the colour-colour diagram the reddening is estimated to be 1.25mag. Comparison of the observational colour–magnitude diagrams (CMDs) with the convective core overshoot models (Bertelli et al. 1994) produces a good fit for a metallicity Z = 0.008 and age of 0.6 - 0.8 Gyr. An apparent distance modulus (m-M) of 15.6 has been estimated for King 7 which puts it at a distance of 2.2 ± 0.34 kpc from us.
