In this article, I reflect on Benedict Anderson's work on Indonesian urbanism. There are at least three concepts from Anderson's work, particularly Imagined Communities, which deserve further attention in Indonesia's urban studies, namely: 1) political cultures; 2) territorial boundaries; and 3) the urban scale of imagined communities. Besides the conceptual dimensions, the perspectives of Anderson's work that featured ethical stance and strong commitments are useful principles in studying urbanisms in Indonesia, particularly in dealing with pragmatism in urban development. The three conceptual dimensions, along with the critical stance toward political and economic elites, point towards paying increased attention to marginalized communities in conducting urban research.
