This paper poses the question of what the proliferation of urban research centres across the world means for urban studies as a field of research, what this tells us about the (uneven) geographies of urban knowledge production and circulation, and who are the key institutions and researchers involved. In other words: what, where and who is urban studies? Building on a minor tradition of bibliometric research in urban studies and related disciplines, the paper assesses the Scopus-registered 2011–2021 publication output of the more than 1000 researchers affiliated to 30 urban studies centres across the world. The analysis points to four main observations. First, urban studies output is published in an extraordinarily wide range of journals, representing work from research communities across the social sciences and humanities, engineering, natural sciences and medical sciences. Second, clear global hierarchies exist in knowledge production, but co-authorship relations are also shaped by geographical proximity and the multidisciplinary profile of each individual research centre. Third, English is the dominant language of academic publications, but other languages play important roles for individual centres at the level of co-authorship relations and journals. Fourth, the article provides evidence of a diverse and globally distributed landscape of mid-sized urban studies centres that contribute substantially to the top urban studies journals. Each observation is linked to a reflection on the potential role for research centres in creating a more equal playing field for urban studies.
