The weak hadronic decay D0K0K+K- is observed in a data sample of 9.3 pb-1 collected with the Mark III detector at the (3770) resonance. An analysis of the K+K- subsystem suggests that while the decay proceeds in part through the K0 channel, providing evidence for the presence of nonspectator amplitudes in D0 decays, a significant fraction of the decays occurs through both higher- and lower-mass K+K- systems. A limit is set on the decay D0K0K0, also thought to proceed by nonspectator processes.
