The London Nocturne (formerly the Smithfield Nocturne) was a cycling race in London, England, organised as a criterium around a long course in the City of London. It was first run in 2007 for men and in 2009 for women, and took place as part of a celebration of cycling during the afternoon and evening, such as those involving penny-farthings and folding bicycles. Despite not being on the UCI Europe Tour, the race nonetheless attracted some high-profile names, such as Ed Clancy, Mark Cavendish, Matthew Goss, Davide Appollonio, Magnus Bäckstedt, and Sarah Storey.
