Starting from an understanding that maps of an entire nation-state territory reflect and regulate state projects and expressions of national identity, rather than providing detailed technical information for decision making, this paper examines the national maps of race/ethnicity produced under Ecuador's state-led multiculturalism. Using national-scale cartography as a means to examine contested processes of rearticulating state, citizen and nation, the paper analyses recent transformations in cartography, nation building and geographical knowledge in Ecuador. Directing a critical analysis towards the ways maps of indigenous populations are produced, circulated, authorised and read provides a distinctive lens by which to explore postcolonial questions of belonging, rights and presence. The paper discusses how, despite the emergence of innovative maps, the plurinational project envisaged by indigenous cartographers remains stymied by a series of material, cultural and postcolonial limitations.
