When an adaptation of a work has a different title than the source material. This often happens because the original title was deemed unsuitable for the medium it was adapted into – a title that sounds fine for a book may sound awkward for a film, and possibly difficult to understand if the original work has a premise that may not be familiar to mainstream audiences. The title may also be changed because it sounded too similar to an unrelated work. Or perhaps the producers simply wanted a better name.
Depending on how different the title and/or story are, this can lead the work to be seen less as an adaptation and more as a work influenced by the original, since now the title can't tie the two together. Taken to the extreme, the work ends up as a Divorced Installment, erasing all association with whatever it was based on.
A Market-Based Title, where the name is changed in international versions, may involve this, or it may reverse the trope and use the original work's title. This depends on how well the original story is known abroad.
Adaptation Displacement is a very frequent symptom of this trope if the original story is unknown to a wider audience.
See also Adaptation Name Change (when something in-story has its name changed), Appropriated Title (when a franchise that began with a work of a particular title is better known by the name of a later installment in said franchise) and compare In Name Only (when the name is (usually) kept, but most or all of the content is different).

- Masters of the Universe toyline was adapted as He-Man and the Masters of the Universe first in 1983 and later a reboot in 2002. The only media that adapted the same name as the original toyline is the 1987 movie.
- She-Ra and the Princesses of Power is an adaptation of the original She-Ra: Princess of Power. The title change reflects how Adora isn't or doesn't know she's a princess in the reboot as she never finds her biological family in this version, and the "princess(es) of power" instead refers to her princess allies now rather than herself.
- Static Shock is based on Static.
- Thomas & Friends:
- When The Railway Series got adapted to television, the title was changed to Thomas the Tank Engine & Friends (later shortened to Thomas & Friends), placing much more emphasis on Thomas compared to the novels. Later rereleases of the novels would end up using the Thomas the Tank Engine title alongside the original title.
- In an interesting case of this trope being combined with Market-Based Title, the US airings of the first 4 seasons (which were largely adaptations of the stories in The Railway Series) often go by different titles than the UK airings, which mostly stuck to the original titles in the novels (bar some exceptions). For one example, the UK title of the first episode (and the title of the story it's based on), "Thomas and Gordon", was retitled entirely to "Thomas Gets Tricked" in the US.
