Four unannounced LEGO sets from ever growing Harry Potter line have been spotted online via some official-looking images ahead of their summer 2026 release. The leaked products include some adorable designs, such as a compact LEGO replica of Hagrid's baby dragon Norbert.
Harry Potter is one of a select few evergreen LEGO themes based on licensed IP, with the Danish toymaker historically renewing the line several times a year. LEGO has already introduced a significant wave of news Harry Potter sets in January 2026, including 76470 Enchanted Flying Ford Anglia, 76467 Luna Lovegood's House and 76466 Philosopher's Stone: Collectors' Edition. A month later, the company launched 30724 Dumbledore's Office with Harry Potter, a 42-piece polybag that is currently its latest Harry Potter file.
LEGO Harry Potter Summer 2026 Wave includes Hagrid's baby dragon and more
Four new ones Harry Potter the sets have now been spotted online and appear from two sources. 76478 Book Nook: Dumbledore's Office was shared by LEGO leaker Lite, while three others were found on French retailer FNAC's website. The final trio includes 76473 Hogwarts Castle: East Wing, 76474 Hogwarts Herb Plants and 76477 Norbert: Hagrid's Baby Dragon. Most of the leaked models have already been detailed in previous LEGO Harry Potter rumors, but this is the first time any of them have actually been spotted.
Newly leaked LEGO Harry Potter sets
In terms of cuteness, 76477 Norbert: Hagrid's Baby Dragon easily stands out from the newly leaked batch. Rumored to retail for $49.99, it features a tiny dragon with fully extended wings and a body emerging from a large cracked egg. So it seems to show the very scene where Norbert hatches Harry Potter and the Philosopher's Stone. It is reported that the set's summer 2026 launch window may be timed to take advantage of HBO's upcoming broadcast Harry Potter The TV show, whose first season is scheduled to premiere on December 25, is expected to feature Norbert. The leaked box confirms the earlier rumor of 76477 Norbert: Hagrid's Baby Dragon consisting of 482 pieces.
Among the other three leaked files, Hogwarts Castle: East Wing continues the trend of partial Hogwarts Castle rereleases. Another similar model, 76463 Hogwarts Castle: Hospital Wing, debuted in January 2026 with a price tag of $99.99. The East Wing is expected to retail for $269.99, which may reflect its much larger unit count, with the leaked box showing 2,164 units, up nearly 140% compared to the Hospital Wing's 907 unit count. Separately, 76474 Hogwarts Herbal Plants will apparently mark the second LEGO rendition of Mandrake to date. The Danish toymaker previously released a standalone Mandrake set (76433) in June 2024. The 579-piece model was discontinued in November 2025.

No reliable source has yet announced a firm release date for any of the newly leaked sets. However, LEGO's summer 2026 release wave is widely rumored to be centered on August, making it a prime candidate to launch these four products. Previous leaks also pointed to a smaller September 2026 wave that would include a LEGO rendition of the Ministry of Magic. With figures of nearly 3,500 pieces, this model is expected to rank among the largest Harry Potter sets to date.
