  We present results of a search for OB associations in NGC 300. Using an
automatic and objective method (PLC technique) 117 objects were found.
Statistical tests indicate that our sample is contaminated by less than 10 % of
spurious detections due to random concentrations of blue stars. Spatial
distributions of detected associations and H II regions are strongly
correlated. The size distribution reveals a significant peak at about 60
$\mu$rad which corresponds to 125 parsecs if a distance modulus of 26.66 mag is
assumed. Besides the objects with sizes corresponding to typical associations
we also found several much larger objects. A second level application of our
detection method revealed that most of these are composed of smaller subgroups,
with sizes of about 100 pc.
