We discuss how matter-enhanced active-sterile neutrino transformation in the νe⇌νs and ν̅ e⇌ν̅ s channels could enable the production of the rapid neutron capture (r-process) nuclei in neutrino-heated supernova ejecta. In this scheme the lightest sterile neutrino would be heavier than the νe and split from it by a vacuum mass-squared difference of 3 eV2≲δmes2≲70 eV2 with vacuum mixing angle sin22θes>10-4.
