A practical joke device is a toy intended to confuse, frighten, or amuse individuals as a prank. Often, these toys are harmless facsimiles of disgusting terrifying objects, such as vomit or spilled nail polish. In other instances, they are created as seemingly harmless items designed to humorously malfunction in such a way as to confuse or harm the target of a prank. The devices are frequently sold in magic or specialty shops, purchased over the Internet, or crafted for oneself. The most notable joke device is the whoopee cushion.

Although commonly employed at events and gatherings, practical joke devices are sometimes seen in everyday life, either as a mechanism of play by children, or among adult co-workers in a work environment. In addition to commercially manufactured practical joke devices, everyday objects have been converted into joke devices by purveyors of pranks.
