Abstract: Background: This article surveys recent engagement with infrastructure across several fields, with particular attention to analyses of the relationship between infrastructure, extractive capitalism, and settler colonialism.  Analysis: The article treats infrastructure as a form of non-discursive politics and examines the critical status of the concept in light of the historical and contemporary implications of infrastructure in colonialism, settler colonialism, and racial capitalism. Conclusions and implications: The article concludes that treatments of infrastructure in recent critical feminist, queer, and Indigenous thought open new possibilities for rethinking politics, communication, and media.
