A bigroupoid is a bicategory with invertibility conditions. For example, a topological space has a homotopy bigroupoid. There are also algebraic examples got by combining crossed modules with group actions. In this paper the authors construct a nine-term exact sequence associated to a fibration of bigroupoids, and give applications in topology and algebra.
