The wizards didn’t even have time to raise their wands as the images were already circulating online. The new LEGO Harry Potter sets planned for summer 2026 have leaked, revealing models that should appeal to both 2000s nostalgic fans and new Hogwarts fans.
Relayed by the Czech media Letem svetem Applem under the pen of Jiří Filip, the information is already causing a stir among collectors. Several visuals show the return of iconic locations like Diagon Alley and Knockturn Alley, as well as a highly anticipated new version of Dobby. If LEGO has not yet officially confirmed these releases, the new products should be available this summer.
The new LEGO Harry Potter 2026 sets already visible online
The tone is set from the title published by the specialist media: “New LEGO Harry Potter sets have leaked online! You’re going to want them at home.” The first images show a series designed as a decorative showcase around the coats of arms of the Hogwarts houses. The whole thing seems designed to sit on a shelf, in a spirit close to collections intended for adults.
Another surprise, the return of Diagon Alley in a darker version. According to leaks, Knockturn Alley is larger and much more detailed than previous editions. A choice that clearly seems to be banking on the nostalgia of the first Harry Potter sets from the early 2000s, while adopting today’s more refined construction standards.

Diagon Alley and Allée des Embrumes, the challenge of modernized nostalgia
The visuals suggest a more immersive atmosphere. The facades appear densified, the interiors more elaborate and the architectural details reinforced. This positioning is not trivial: LEGO has been targeting adult collectors as much as children for several years.
The media also mentions other leaks in the world of bricks, as evidenced by this title: “Images of LEGO Shrek have leaked online! Discover the first photos of the most anticipated sets of the year.”
Dobby and the return of Expecto Patronum in bricks
Another emblematic figure of the saga, Dobby would make his comeback. This new version would be more detailed and better proportioned than the previous one. For those who were disappointed by the old figurine, this reinterpretation could correct the situation.
The famous Expecto Patronum spell would also be back. This time, the changes would seem limited. Collectors who already own a LEGO version may not see this as a major development, but newcomers to the Harry Potter universe may find it an accessible entry into the world of magical duels.
A LEGO strategy designed for children and adult collectors
All of the leaked models give the impression of a range built around a dual audience. Young fans will find cult scenes and iconic characters, while adults will be able to enrich their collection with more detailed and decorative pieces.
In the same spirit, other franchises are taking advantage of this renewed interest, as highlighted in this headline: “New photos of LEGO LOTR Minas Tirith have leaked online and we are delighted!”
If these leaks are confirmed in the coming weeks, LEGO could well pull off one of its most anticipated summer launches. The official presentation should take place soon, with marketing announced this summer.
