Postmodernity is characterised by a thoroughgoing alteration in the ways in which space is both experienced and conceived. During the post-war period, social and spatial relations were substantially transformed by the far-reaching effects of economic globalisation, neo-imperial conflicts, new transport and communications technologies, mass migrations, political devolution, and impending environmental crisis. Concurrently, space and geography have become existential and cultural dominants for postmodern societies, to an extent displacing time and history. Given such a spatio-temporal conjuncture, this chapter explores the significance of space for British postmodern fiction and describes some of its characteristic geographies, focusing upon three distinctive kinds of spaces: cities; non-places; and regions. Among the texts discussed are novels by J.G. Ballard, Julian Barnes, Christine Brooke-Rose, Angela Carter, Maureen Duffy, Alasdair Gray, Hanif Kureishi, Salman Rushdie, Iain Sinclair, Zadie Smith, Graham Swift, Adam Thorpe, and Jeanette Winterson.
