As part of an ongoing photometric survey of young Magellanic Cloud clusters we identified Be stars in NGC 1818 and a nearby smaller cluster in the Large Magellanic Cloud. The neighbouring cluster does not contain evolved stars, and its sparsely populated main sequence does not extend to stars as massive as in NGC 1818. Both clusters are younger than the surrounding field population and contain a much higher Be star fraction. We present a table with photometry, astrometric positions, and IAU-conform identifiers of the Be stars. We compare Be star fractions in Magellanic Cloud clusters and Galactic open clusters and discuss possible constraints on Be star theories.
