It’s been an exciting month of deals and new reveals from LEGO, but now we’re approaching one of the most exciting parts of every month – new LEGO sets hitting the shelves! Once the clock ticks us over to September, you can score any of the following 17 new sets – plus, some GWP sets, too! Head on down below to check out the latest lineup to join the available sets.

While we’re not seeing as massive a lineup as August’s 97-set launch, September does still have plenty to be excited about hitting shelves at midnight, like the 2026 Advent Calendars. That’s not all, as DC fans can get their hands on the Batman Returns Batmobile set, Marvel fans can grab the Doctor Doom Bust set, and Icons fans can grab new builds like the SpongeBob SquarePants: Bikini Bottom or the Star Trek: U.S.S. Enterprise NCC-1701 Bridge, among others. Of course, this is a Harry Potter-dominated month, with GWPs primarily focusing on the theme, not to mention the release of the massive Ministry of Magic – Collectors’ Edition set.

This month’s GWP sets include:

Ministry Munchies & The Daily Prophet Stands GWP upon spending $130 or more on LEGO Harry Potter sets until September 6, 2026, or until stock runs out.
Ministry of Magic Phone Booth GWP upon purchasing the The Ministry of Magic – Collectors’ Edition until September 6, 2026, or until stock runs out.
