Lucy Clare D'Orsi, CVO, QPM (née Copson; born December 1969) is a British police officer.

In 2004, Lucy and Raffaele D'Orsi were thanked by author Lynda La Plante for their advice on police procedures for her novel Above Suspicion.

She was in charge of the police response to London's largest fire of 2006, in Beaufort Park, Hendon, and has headed special operations relating to illegal weapons.

In 2015, D'Orsi was in charge of security during the visit of Chinese leader Xi Jinping to the United Kingdom[6][7] which was regarded on the British official side as a very difficult visit to arrange as in negotiations the Chinese delegation had wanted their security officials to be able to carry guns and for all anti-Chinese protests to be banned, neither of which demands was agreed to by the Metropolitan Police.

[8] In May 2016, Queen Elizabeth II was filmed remarking that the Chinese "were very rude to the ambassador", and that it was "bad luck" for D'Orsi to be responsible for security during the visit.
