  We present results concerning the occurrence of Seyfert galaxies in a new
large sample of Compact Groups (Focardi & Kelm 2002). Seyfert galaxies turn out
to be relatively rare (<3%), with a significant dominance of Sy2. Seyferts are
preferentially associated to Compact Groups displaying relatively high velocity
dispersion and a large number of neighbours. These characteristics,together
with an excess of ellipticals among companions, suggest that Seyferts are to be
found preferentially in rich-groups/poor-cluster like CGs.
