Lt. Tawny Madison is the heroine of the fictional television series Galaxy Quest and the computer officer of the NSEA-Protector, portrayed by Gwen Demarco (Sigourney Weaver).


In the original series, Lt. Tawny Madison was the show's heroine and sex symbol, and the only female member of the crew. Her character is mostly unevolved as a heroine, and her job on the crew consists only of talking with the ship's computer AI, or simply put, repeat whatever the computer says, despite everybody already hearing its voice.

In the series, there were subtle hints that she may have had romantic feelings for Commander Peter Quincy Taggart, which is highly speculated by enthusiastic female fans of the series.

In the sequel series, Galaxy Quest: The Journey Continues, Gwen Demarko reprises her role as Lt. Madison.


  • Gwen Demarko/Tawny Madison is portrayed by actress Sigourney Weaver, who is no stranger as a heroine of scifi movies. Weaver compared her meta-fictional role as Tawny to her role as Ellen Ripley in the Alien series, describing Tawny as "a stereotypical dumb blonde" who fulfills a useless function in contrast to Ripley's dynamic centrality.
