seaQuest DSV is an American science fiction television series created by Rockne S. O'Bannon. It originally aired on NBC between 1993 and 1996.

Set in "the near future", seaQuest originally mixed high drama with realistic scientific fiction. It starred Roy Scheider as Nathan Bridger, captain of the eponymous high-tech submarine seaQuest DSV 4600, Jonathan Brandis as Lucas Wolenczak, a teenaged computer genius, and Stephanie Beacham as Kristin Westphalen, the chief medical officer and head of the seaQuest science department. Steven Spielberg expressed interest in the project and served as one of the show's executive producers during the first two seasons.

The 21st century: mankind has colonized the last unexplored region on Earth; the ocean. As captain of the seaQuest and its crew, we are its guardians. For beneath the surface lies the future.
