A magic mug, also known as a heat changing mug, transforming mug, or disappearing mug is a mug that changes color when it is filled with a hot liquid. This effect is created by using thermochromic ink.

Magic mugs are often manufactured and sold as memorabilia. For example, a mug may reveal a picture of the town or monument where it was sold, for example the Haunted Mansion/Grim Grinning Ghost Disney cup.{{Cite web|last=Coffey|first=Kelly|date=2020-05-28|title=Heat Sensitive Haunted Mansion Themed Coffee Mug Materializes Into Disney World|url=https://insidethemagic.net/2020/05/heat-sensitive-haunted-mansion-mug-kc1/|access-date=2022-02-23|website=Inside the Magic|language=en-US}} They are sometimes given away to promote organizations. Customers can also have their own photographs printed on the mugs.{{Cite web|last=Tansill-Suddath|first=Callie|date=19 July 2018|title=This Color-Changing Photo Mug Will Let You Surprise Your BFF With A Secret Picture|url=https://www.bustle.com/p/this-color-changing-photo-mug-will-let-you-surprise-your-bff-with-a-secret-picture-9817520|access-date=2022-02-23|website=Bustle|language=en}}

In 2017, Panasonic introduced the concept of "smart magic mugs" when it showcased an in-car display table/screen that automatically rearranges the digitally displayed information around a mug when the latter is placed on it.{{Cite web|date=2017-01-08|title=Panasonic's autonomous car cabin sits you at an interactive display table|url=https://newatlas.com/panasonic-autonomous-cabin-concept/47280/|access-date=2022-02-23|website=New Atlas|language=en-US}}
