I will present nested operads, which generalize operads of various kinds (May, cyclic, modular, PROPs, Batanin's theory of globular operads, etc.), by allowing operations to be organized in hierarchies. This provides, for example, a unifying framework for  different models of higher categorical structures, or higher dimensional fundamental groupoids. I will describe connections to existing theories of higher dimensional operads.
