In this paper, we characterize the possible cofinalities of the least-strongly compact cardinal. We show that, on the one hand, for any regular cardinal,, that carries a-complete uniform ultrafilter, it is consistent, relative to the existence of a supercompact cardinal above, that the least-strongly compact cardinal has cofinality. On the other hand, provably the cofinality of the least-strongly compact cardinal always carries a-complete uniform ultrafilter.
