Stormbringer is a magic sword featured in a number of fantasy stories by the author Michael Moorcock. It is described as a huge, black sword covered with strange runes, created by the forces of Chaos. The sword has a will of its own and it is hinted that the sword may be controlled by an inhabiting entity. It is wielded by the doomed albino emperor Elric of Melniboné. Stormbringer makes its first appearance in the 1961 novella The Dreaming City. In the four novellas collected in the 1965 book Stormbringer, the sword's true nature is revealed.
