Neutrinos play an essential role in determining the outcome of formation of nuclei in core-collapse supernovae or in the neutrino-driven winds of neutron star mergers. It has been shown in recent years that neutrino oscillations among active flavors or between the active and a possible sterile state may happen in these astrophysical environments to influence the result of nucleosynthesis. We have examined in detail the effect of neutrino oscillations on different nucleosynthesis processes in these astrophysical environments and the results will be discussed.
