''Lupin III Vs Detective Conan'' is not counted in the MadeForTVMovie ''Lupin'' anime specials by the Japanese. It is included on the Anime/LupinIIIYearlySpecials index for completeness. It debuted on March 27, 2009, and has yet to have an official English language release.

A direct-to-video CrossOver of the ''Franchise/LupinIII'' and ''Manga/DetectiveConan'' series.

Queen Sakura, sovereign of the [[{{Ruritania}} European kingdom of Vespania]], is killed while the royal court (her brother and son) are out hunting. All indications suggest that she was accidentally shot by her son, Prince Gill, who immediately commits suicide, overcome by guilt. This news is reported around the world, with a [[AsYouKnow reminder to the audience]] that Vespania was already recently in the news, because of the strange new minerals found only there.

With the death of the queen and prince, the young but bratty Princess Mira is next in line. However, Vespania citizens are rallying to say the princess is too young and unfit to govern. To increase the princess' popularity, a trip to Japan is organized. A festival is held at the Grand Hotel West City Tama. Despite her protests, Mira attends the opening, though Keith does all the talking for her. Kogoro Mouri, Sonoko Suzuki, and Conan Edogawa attend (Ran Mouri is running late). At the party, Conan exposes an attempt to assassinate the princess. The princess wants nothing more than to escape from her [[GildedCage condition]], so in the confusion that follows, she sneaks away. Conan notices this, and follows her. Mira runs into Ran, [[IdenticalStranger who looks identical]]. They trade places, Ran returning to the hotel. Mira gets picked up by Fujiko. Conan notices the two splitting up, and Conan pursues Fujiko on skateboard.

Lupin's team is already involved in some plan by the time Conan arrives in Vespania. Can the two team up to keep the princess on the throne, or will she fall victim to assassination or suicide? Was the late Queen's death an accident, or has Conan stumbled upon another murder? No matter what crime, no matter who is involved, no matter how complicated the deduction, with a keen eye for details, only one truth prevails!

The sequel is ''Anime/LupinIIIVsDetectiveConanTheMovie.''

!!''Lupin III vs. Detective Conan'' contains examples of:

* AnAesop:
-->'''Conan:''' ''(To Lupin)'' Stealing is bad, mister.
* AnimationBump
* AntiHero: Lupin and the gang are heroes this time, well, except for Fujiko. [[spoiler: Lupin's attempt to steal the crown jewels are actually part of a promise he made to the recently deceased queen. She wanted to escape her gilded cage, just as Mira does, and Lupin said he would return to steal the crown when she had made her kingdom great. That promise gave her confidence, and helped Mira's confidence as well.]]
* BodyDouble: Ran to Princess Mira.
* TheCaper: Lupin's motivation at the start of the movie.
* CanonWelding: Alluded to when Kogorou notes he thought Lupin III was just a manga character. He's assured that he's very real, and, well, for the purpose of the special and its sequel...
* CherryBlossoms: The movie involves a blossoming cherry tree as a major plot point related to the murder that takes place during the opening act.
* CrossOver: Between ''Franchise/LupinIII'' and ''Manga/DetectiveConan''.
* DoubleStandardAbuseFemaleOnMale: It's OK for Fujiko to "examine" Conan to find "the secret to rejuvenation." Yes, the scene of a fully grown woman apparently (we only got the audio) touching a little boy is treated comedically.
* EmergencyImpersonation: Lupin disguises himself ''again'' [[spoiler: but this time, as Detective Moore!]]
* EnemyMine: Lupin and his gang helps Conan [[spoiler: catch the criminals and return to Japan.]]
* EvilChancellor: He's the Big Bad, because he murdered his Queen and the Crown Prince of his land, and attempts to murder the SoleSurvivor of the royal family, the BrokenBird Princess. In this case, he was never regent, merely next in line to the throne, and upset his advice wasn't being followed by the Queen.
* FriendlyEnemy: Lupin and Conan, despite the animosity, they clearly respect each other by the time the movies over.
* IdenticalStranger: Ran and Princess Mira. Prince Gill (Mira's sister and one of the victims) and Shinichi, except for differing hair color and style. (This one's actually never alluded to, which is probably for the best given the opportunity for awkward IncestSubtext.)
* IntercontinuityCrossover
* TheKingdom: The kingdom of Vespania.
* LeaningOnTheFourthWall: When asked how a professional detective like him is unaware of the existence of the world's most famous thief, Kogoro says he always thought Lupin was [[MythologyGag just a comic book character]].
* LighterAndSofter: Compared to both ''Manga.LupinIII'' and ''Manga/DetectiveConan'', the film has only two murders, and both are offscreen.
** It's still a little DarkerAndEdgier than your average ''Conan'' movie, though, in how politics play a role in the plot. There's even a scene where Lupin and Jigen discuss the possibilities of Vespania's new super-stealth mineral being a game-changer in warfare, complete with an ImagineSpot of the White House being attacked by a missile.
* [[PrinceAndPauper Princess and Pauper]]
* PrincessForADay
* ProperLady: Queen Sakura.
* {{Secret Keeper}}s: Lupin and his gang know Conan's secret.
* ShoutOut: The part involving Ran and Princess Mira is one to all the PrinceAndPauper stories.
* SwitchingPOV: Lots of cutting between Conan's group and Lupin's group.
