Lupin the 3rd vs Detective Conan (Japanese: ルパン三世VS名探偵コナン, Hepburn: Rupan Sansei Vāsasu Meitantei Konan^?) is a Japanese animated crossover television special between the Lupin III and Detective Conan series. It was broadcast on Nippon TV on March 27, 2009. Discotek Media released the television film on DVD in North America on October 27, 2015.

Queen Sakura, sovereign of the European kingdom of Vespania, is killed while out hunting. All indications suggest that she was accidentally shot by her son, Prince Gill, who immediately commits suicide, overcome by guilt. The title of heir to the throne of Vespania passes to Princess Mira, a girl who rejects the throne because she thinks that she's not the rightful heir. The coronation ceremony is threatened by a growing popular movement that believes Princess Mira is unfit to govern. Duke Keith, the chief of Commons, makes Daisuke Jigen, former trainer of Vespania's regular army, a personal guard of the princess. Simultaneously, Arsène Lupin III reaches Vespania; his and Jigen's plan is to get their hands on the crown for the Queens of the Realm.

To increase the princess' popularity, a trip around Japan is organized. A festival is held at the Grand Hotel West City Tama, which Kogoro Mouri and Conan Edogawa attend. At the party, Conan exposes an attempt to poison the princess. The princess wants nothing more than to escape from her condition, so in the confusion that follows, she sneaks away. Conan notices this, and follows her.
