LEGO set 76431, Hogwarts Castle: Potions Class, depicts a potions classroom in the Harry Potter universe. Released in 2024, it belongs to the Harry Potter theme and contains 396 pieces.

Set 76431 focuses on the potions class at Hogwarts Castle, a school setting closely associated with Severus Snape in the Harry Potter licence. Within the theme, it is best understood as an interior classroom scene rather than a large castle exterior or a broad location build.

The set is suited to Harry Potter collectors, to builders assembling Hogwarts interiors, and to play centred on classroom scenes. Among sets from the same theme, it occupies a specific role as a potions lesson, making it a useful companion to other Hogwarts school settings and character based displays.
