We present CCD data in the Johnson passbands B and V of the young association NGC 1962-65-66-70 in the Large Magellanic Cloud. We find the association to show an age spread in the range 4 to 9Myr. Some signs for a propagation of star formation from the south-eastern to the northern part of the region can be found, but they are based on very few stars. The slope of the luminosity function is γ=0.27±0.02 for stars of the magnitude range -8<M_V<+2mag. The slope of the initial mass function is x=1.2±0.1 in the mass range 2.5<M<20M_☉ which is compatible with the value for the solar vicinity (x=1.35). We discuss some of the bright stars, in particular the star HDE 269551, which turns out to be a multiple system.
