Nuclear magnetic resonance is a powerful probe of the unconventional new phases that often emerge at low temperature in actinide compounds. NMR of both the ligand (non-f electron) sites and the actinide site itself can be performed, and each reveals important information about the low energy electronic degrees of freedom. Data will be presented in both the ordered and disordered states of superconducting and magnetic plutonium and uranium compounds, and the implications for the behavior of the strongly correlated electrons in these systems will be discussed.
