2016 Six Days of London was a professional track cycling event held at the Lee Valley VeloPark over six consecutive days from 25 to 30 October 2016. It was the second year the event was held since the historical Six Days of London event was resurrected in 2015. Before the event, the organisers announced that the event was to form part of a "Six Day Series", with the London event being followed by events in Amsterdam, Berlin and Copenhagen, with a "final" then being held at the Palma velodrome in Mallorca.
