This article is about Bing's theorem on 3-manifolds. For Bing's metrization theorem, see Bing metrization theorem. For Bing's example of a product of non-manifolds, see Bing's example.

In topology, Bing's theorem, named for RH Bing, asserts that a necessary and sufficient condition for a 3-manifold M to be homeomorphic to the 3-sphere is that every Jordan curve in M be contained within a topological ball.
