A "goodie" is an English term used to refer to a derivative product or merchandising item related to a franchise, artistic work, movie, television series, anime, video game, or any other popular media. Goodies are often promotional items intended to be purchased and collected by fans.

Goodies can take various forms, ranging from small items like keychains, stickers, pins, or badges, to larger items such as t-shirts, bags, figurines, posters, plush toys, and many more. They can also include accessories related to the characters or the universe of the work, such as mugs, pouches, wallets, notebooks, phone cases, etc.
