For any orbifold M , we explicitly construct a simplicial complex S(M ) from a given triangulation of the ‘coarse’ underlying space together with the local isotropy groups of M . We prove that, for any local system on M , this complex S(M ) has the same cohomology as M . The use of S(M ) in explicit calculations is illustrated in the example of the ‘teardrop’ orbifold.
