Johnson BV CCD observations have been made of the young Large Magellanic Cloud cluster NGC 2214 and a nearby field using the Anglo-Australian Telescope. It has been suggested in the literature that this elliptical cluster is actually two clusters in the process of merging. No evidence is found from profile fitting or the colour-magnitude diagrams to support this contention. Completeness factors are estimated for the CCD frames. These values are used in conjunction with luminosity functions to estimate the initial mass function (IMF) for NGC 2214. A power law is assumed for the IMF, with a good fit being found for the exponent (1+x)=2.01+/-0.09. There is some indication that the low-mass end (<~3 M_solar) has a lower gradient than the high-mass end of the derived IMF. This value is in reasonable agreement with literature values for other Magellanic IMFs, and not substantially different from those of the poorly determined Galactic IMFs, suggesting the possibility of a `universal' IMF over the Magellanic Clouds and our Galaxy in the mass range ~1 to ~10 M_solar.
