Highlander: The Series is a science fantasy action-adventure television series featuring Duncan MacLeod (Adrian Paul) of the Scottish Clan MacLeod, as the eponymous "Highlander". It was co-produced by Rysher Distribution in the United States, Gaumont Television in France, Reteitalia in Italy, RTL Plus in Germany, and Amuse Video in Japan. An alternate sequel to the 1986 feature film Highlander, it features a storyline in which the protagonist of that film (Connor MacLeod, a member of a race of "Immortals") has not won "the Prize" sought by all Immortals, who still exist post-1985. Christopher Lambert reprised his role as Connor in the pilot episode, which introduced series protagonist Duncan MacLeod, an Immortal who was taken in by the same clan of Scottish Highlanders who had found and raised Connor generations before.

The series was an international hit and was nominated twice for the Motion Picture Sound Editors' Golden Reel Award (Foley Artist ("The Gathering"): 1992; Foley Artist ("The Darkness"): 1993), three times for the Gemini Award (Best Dramatic Series: 1996; Best Performance by an Actor in a Guest Role in a Dramatic Series: 1997 (John Pyper-Ferguson), 1996 (Bruce A. Young)), once for a Saturn Award (Best Genre Syndicated TV Series: 1997), and eight times for the Online Film & Television Association Award (Best Guest Actress in a Syndicated Series (Sandra Bernhard), Best Direction in a Syndicated Series, Best Writing in a Syndicated Series, Best Syndicated Series, Best Ensemble in a Syndicated Series: 1997; Best Actor in a Syndicated Series (Peter Wingfield), Best Syndicated Series, Best Ensemble in a Syndicated Series: 1998).
