Starring Robert Pattinson, Kristen Stewart and Taylor Lautner, the film is part of the vampire franchise based on the novels of Stephanie Meyer.
Illegal street and market sales of the film outstripped sales of all other counterfeit films in Britain, highlighting its popularity, reported Daily Mail.
It is the first time in four years that a Harry Potter film has failed to be the most pirated film at Christmas, according to the annual counterfeit chart.
Other pirated movies highly in demand include 'Avengers Assemble', 'The Hunger Games' and 'Brave'.
