Saban's Adventures of the Little Mermaid (人魚姫マリーナの冒険, Ningyo-hime Marīna no Bōken, lit. 'The Adventures of Mermaid Princess Marina'; French: Le Prince et la Sirène, lit. 'The Prince and the Mermaid') is an animated series produced by Fuji Television and Saban International Paris and animated by Telescreen in the early 1990s, based on the 1837 Hans Christian Andersen fairy tale "The Little Mermaid".

This 26-episode TV series was originally created by Jean Chalopin and directed by Takehiro Miyano. The series was broadcast on Japan's Fuji TV network from February to July 1991. As in the 1975 feature-length film version produced by Toei Animation, Hans Christian Andersen's The Little Mermaid (with which this series may be confused), the mermaid protagonist was drawn as a blonde in this version and given the name Marina. It also added a new ingredient to the story: a magic potion given to the prince which he could use to breathe underwater and be with Marina.

The show was released in the United States for Saturday morning and weekday afternoon syndication by Saban Entertainment in association with USA syndicator Bohbot Entertainment in the summer of 1991, intended to capitalize on the success of the Disney film adaptation of the same story. Disney coincidentally released their own TV series adaptation, which did far better than Saban's in the ratings.

Ownership of the series passed to Disney in 2001 when Disney acquired Fox Kids Worldwide, which also includes Saban Entertainment.
