Lupin season 4 is officially returning to Netflix on October 23, 2026, bringing Omar Sy back as Assane Diop. Netflix has confirmed that all eight episodes will be released on the same day, giving viewers a complete new chapter rather than a weekly rollout.
The upcoming installment is officially called Lupin Part 4 by Netflix. It follows the events of Part 3, which ended with Assane behind bars after finally allowing the authorities to believe that he had been captured. The new story begins four years after those events.
For viewers in the USA, UK, and other Netflix markets, October 23 is the key date to mark. Netflix has already released the official trailer and first-look material, confirming that Assane’s story is far from finished.
What Is Lupin Season 4 About?
The story takes an unexpected turn because Assane is initially trying to leave his criminal alter ego behind. He remains in prison and intends to serve his sentence while keeping a promise to his son to reunite with their family in Senegal. His plans change when a mysterious message signed by Lupin announces a series of simultaneous museum robberies.
The problem for Assane is that the evidence points directly toward him.
According to Netflix’s official synopsis, cameras even appear to place Assane inside one of the museums during a robbery in which Captain Belkacem is seriously injured. Assane insists that he is innocent, leaving him with a difficult problem: if he did not organize the crimes, someone is deliberately copying his methods and identity.
That setup gives the new story a different starting point from earlier parts. Instead of simply planning another elaborate theft, Assane has to discover who is using the Lupin identity while also trying to prove his own innocence.
A New Mystery for Assane
The copycat mystery could also give the series another opportunity to connect its modern storyline with the literary legacy of Arsène Lupin.
The Netflix series is inspired by the character created by French author Maurice Leblanc. Assane has always borrowed ideas, disguises and techniques associated with the gentleman thief, but Part 4 appears to push that connection further by placing the Lupin identity at the center of a crime that Assane claims he did not commit.
Lupin Season 4 Cast
Omar Sy returns as Assane Diop, the central character who has driven the series since its debut. Netflix has also confirmed the return of several familiar cast members.
| Actor | Character / Role |
|---|---|
| Omar Sy | Assane Diop |
| Ludivine Sagnier | Claire |
| Antoine Gouy | Benjamin |
| Soufiane Guerrab | Detective Guédira |
| Shirine Boutella | Sofia Belkacem |
| Théo Christine | Confirmed returning cast member |
| Laïka Blanc-Francard | Confirmed returning cast member |
The returning ensemble is important because Assane’s story has never been only about elaborate robberies. His relationships with Claire, his family and the people investigating him have repeatedly shaped the consequences of his choices.
Netflix identifies Omar Sy as both the returning star and one of the show’s showrunners alongside Louis Leterrier. The series was created by George Kay in collaboration with François Uzan and is produced by Gaumont with Carrousel Studios.
💡 Pro Tip:
If you want to remember the story before watching the new episodes, revisit the ending of Part 3 rather than restarting the entire series. The prison storyline is the direct bridge into Part 4.
How Many Episodes Will There Be?
Lupin season 4 will contain eight episodes, with all eight scheduled to arrive on Netflix on October 23, 2026.
That makes the new installment the same general eight-episode format associated with the show’s previous parts. Netflix’s official synopsis suggests that the central mystery will revolve around the museum robberies, the person copying Assane’s methods, and his attempt to clear his name.
The simultaneous release also means viewers can choose between watching the entire story quickly or spacing the episodes out. Because the series is built around disguises, reversals and revelations, watching several episodes close together may make it easier to follow the developing mystery.

What the Trailer Reveals
The official trailer confirms that Assane is still at the heart of the story, but his circumstances have changed significantly. He begins Part 4 as a prisoner rather than a fugitive moving freely through Paris.
The trailer also reinforces the idea that the Lupin identity has become something larger than Assane himself. Someone is apparently using the name and methods associated with him, creating a situation in which his greatest advantage—his reputation for elaborate deception—can also become evidence against him.
That creates a natural question for the new episodes:
Who is behind the copycat robberies, and why frame Assane?
Netflix has not publicly revealed every major plot development, so viewers should expect the series to keep its biggest twists for the episodes themselves.
Why the New Story Matters
One of the defining features of the French crime thriller has been its combination of heist storytelling, family drama, mystery and the mythology surrounding Arsène Lupin. The official Netflix description continues to classify the series across genres including thriller, mystery, action and drama.
Lupin season 4 therefore does not simply continue another robbery storyline. It places Assane in a situation where the identity he has used to outsmart others may be turned against him.
That shift could also create more tension between Assane’s personal goals and his criminal reputation. He wants to fulfill his promise to his son, yet the appearance of a new Lupin forces him back into a world he was attempting to leave.
