Along with the LEGO NINJAGO theme celebrating its 15th anniversary, the LEGO Harry Potter line is celebrating an even bigger birthday in 2026. And thanks to retailer Wave Distribution, we already have our first look at one of eight Harry Potter-branded sets launching on the 1st of January 2026. This set, like many models releasing over the next 12 months, directly celebrates the theme's anniversary with exclusive branding and collectable items included in the build.


The set itself is 76464 Cauldron: Secret Potions Classroom, which includes a total of 652 pieces retailing for $59.99 / €59.99 / £54.99. The 10+ model is very similar in style to previous LEGO Harry Potter Hogwarts Moments sets, with a literal brick-built LEGO cauldron that can be opened up to reveal a hidden potions classroom inside.




The cauldron's exterior is basically entirely black apart from a printed element of the Hogwarts coat of arms. The cleverly articulated build sits on four brown feet with a matching brown rod coming out of the top of the cauldron, along with some blue and purple liquid. The rod itself can be stirred to reveal the detailed potions classroom found inside.


The potions classroom includes removable tables, bottles and ingredients along a printed/stickered blackboard. Here you can also find one of the 14 collectable Hogwarts portraits, which is included in the 10+ model alongside Hermione's otter Patronus, a part of a special anniversary series of Patronus figures. Two LEGO Minifigures of Hermione herself and Professor Snape are also featured in the $60 2026 set.
