Four unannounced LEGO sets from the ever-growing Harry Potter line have been sighted online via some official-looking images ahead of their summer 2026 release. The leaked products include several adorable designs, such as a compact LEGO replica of Hagrid’s baby dragon, Norbert.
Harry Potter is one of LEGO’s select few evergreen themes based on licensed IPs, with the Danish toymaker historically refreshing the line several times a year. LEGO already introduced a sizable wave of new 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 set.
LEGO Harry Potter Summer 2026 Wave Includes Hagrid’s Baby Dragon and More
Four new Harry Potter sets have now been sighted online, emerging via two sources. 76478 Book Nook: Dumbledore’s Office was shared by LEGO leaker Lite, while three others were found on the website of French retailer FNAC. The latter trio includes 76473 Hogwarts Castle: East Wing, 76474 Hogwarts Herbology 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 sighted.
Newly Leaked LEGO Harry Potter Sets
In terms of cuteness, 76477 Norbert: Hagrid’s Baby Dragon is easily the standout from the newly leaked batch. Rumored to retail for $49.99, the set depicts the tiny dragon with its wings fully spread and its body emerging from a large cracked egg. It thus appears to depict the very scene where Norbert is hatched in Harry Potter and the Philosopher’s Stone. The set’s rumored summer 2026 launch window may be timed to capitalize on HBO’s upcoming Harry Potter TV show, whose first season is scheduled to premiere on December 25 and expected to feature Norbert. The leaked box confirms an earlier rumor about 76477 Norbert: Hagrid’s Baby Dragon consisting of 482 pieces.
Among the other three leaked sets, 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 $99.99 price tag. The East Wing is expected to retail for $269.99, which may reflect its much larger piece count, with the leaked box showing 2,164 pieces, nearly 140% more compared to the Hospital Wing’s 907-piece count. Separately, 76474 Hogwarts Herbology 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 retired in November 2025.

No credible source has yet reported a firm release date for any of the newly leaked sets. However, LEGO’s summer 2026 release wave is widely rumored to be concentrated in August, making that the leading candidate for the four products’ launch window. Previous leaks have also pointed to a smaller September 2026 wave, which is expected to include a LEGO rendition of the Ministry of Magic. With a rumored piece count of nearly 3,500, that model is expected to rank among the largest Harry Potter sets to date.
