  Stars of ~8-100 solar masses end their lives as core-collapse supernovae
(SNe). In the process they emit a powerful burst of neutrinos, produce a
variety of elements, and leave behind either a neutron star or a black hole.
The wide mass range for SN progenitors results in diverse neutrino signals,
explosion energies, and nucleosynthesis products. A major mechanism to produce
nuclei heavier than iron is rapid neutron capture, or the r process. This
process may be connected to SNe in several ways. A brief review is presented on
current understanding of neutrino emission, explosion, and nucleosynthesis of
SNe.
