We review the observational status of the supernova/gamma-ray burst connection .
Present data suggest that SNe associated with GRBs form a heterogeneous class of objects including both bright and faint hypernovae and perhaps also ‘ standard ’ Ib/c events .
Evidence for association with other types of core-collapse SNe ( e.g .
IIn ) is much weaker .
After combining the local GRB rate with the local SN-Ibc rate and beaming estimates , we find the ratio GRB/SNe-Ibc in the range \sim 0.5 \% - 4 \% .
In most SN/GRB associations so far discovered , the SN and GRB events appear to go off simultaneously .
In some cases data do not exclude that the SN explosion may have preceded the GRB by a few days .
Finally we discuss a number of novel questions started by recent cases of GRB-SN associations .
