Merchandise (often shortened to just merch) is a product sold as promotion for a piece of media. Due to Undertale's success, various merchandise items have been produced since the game's release in 2015. Official Undertale merchandise has primarily been produced and sold through Fangamer, with additional merchandise being released through other companies and collaborations.
Undertale has received a wide variety of merchandise based on its characters, locations, items, and other elements of the game. This includes clothing, plush toys, figures, accessories, music releases, books, and other collectibles. The success of Undertale's merchandise also contributed to Deltarune receiving its own extensive range of merchandise beginning in 2018.
