Nairn's London is a 1966 book about the architecture of London. It is authored by British writer Ian Nairn and this is the work for which he is the best known. Architecture critic Jonathan Meades has praised the work as an "imperious mongrel: part vade-mecum, part polemic, part poetic contemplation, part deflected autobiography and part conversation with himself – wholly original" and "the testament of a man steeped in London".
