A search for WR stars in five associations of the Sc galaxy NGC 300 has permitted to better locate, in crowded regions, some of the already known objects and to discover six new WR stars. The on-line/off-line imaging technique was applied using the SUperb Seeing Imager (SUSI) of the ESO New Technology Telescope (NTT) installed at La Silla, Chile. Of the twelve WR stars identified up to now in these associations, three remain to be definitely confirmed by slit spectroscopy, however they have detection significances ≥8σ and can therefore be considered bona fide WR stars. It is argued that after the present survey most, possibly all, of the WR stars contained in the associations studied have been discovered. The average ``O/WR'' ratio of 2.6±0.8 obtained from the comparison of the numbers of WR and zero-age-main-sequence O5 stars is well in the range of the values found for other galaxies, in particular M 33 generally considered as a twin of NGC 300.
