The asymptotic dimension, asdim, of a metric space was defined by Gromov as a quasi-isometric invariant. It was known that a delta-hyperbolic space with bounded geometry has finite asdim. An example is a word-hyperbolic group. We show that the curve graph of a surface has finite asdim. A curve graph is delta-hyperbolic but does not have bounded geometry.
