Nuclear masses have long been recognized as key nuclear physics inputs for calculations of rapid neutron capture, or $r$-process, nucleosynthesis. Here we investigate how uncorrelated uncertainties in nuclear masses translate into uncertainties in the final abundance pattern produced in $r$-process simulations. These uncertainties can obscure details of the abundance pattern that in principle could be used to diagnose the $r$-process astrophysical site. We additionally examine the impact of reductions of mass uncertainties that will come with new experiments.
