Drawing on ethnographic research conducted in 2012 on British Nigerian young women who have gone to boarding school in Nigeria and returned to attend university in the UK, I use the concept of third space as a heuristic device for understanding their transnational subjectivities and practices. I argue that, for some, this third space is a transgressive one in which they can craft alternative subjectivities and narratives about African culture and political economy. Applying insights from decolonial theory, I seek to build on the transgressive nature of this third space. In positioning themselves variously as Londoners, Nigerians, dual and post‐nationals, they express key features of contemporary transnational European subjectivities. Yet, parental expectations that they marry Nigerians and members of the Nigerian diaspora serve to reproduce the racial distinctions and nationalist rhetoric of colonial modernity that their third space subjectivities contest.
