In this paper, we use subword complexes to provide a uniform approach to finite-type cluster complexes and multi-associahedra. We introduce, for any finite Coxeter group and any nonnegative integerk, a spherical subword complex calledmulti-cluster complex. Fork=1, we show that this subword complex is isomorphic to the cluster complex of the given type. We show that multi-cluster complexes of typesAandBcoincide with known simplicial complexes, namely with the simplicial complexes of multi-triangulations and centrally symmetric multi-triangulations, respectively. Furthermore, we show that the multi-cluster complex isuniversalin the sense that every spherical subword complex can be realized as a link of a face of the multi-cluster complex.
