List of episodes

The fourth season of the American science fiction television series Star Trek: Voyager commenced airing on UPN in the United States on September 3, 1997, and concluded on May 20, 1998, after airing 26 episodes. Set in the 24th century, the series followed the adventures of the Starfleet and Maquis crew of the starship USS Voyager after they were stranded in the Delta Quadrant, far from the rest of the Federation. Season Four featured the debut of new main cast member Jeri Ryan as Seven of Nine, nicknamed Seven, and the departure of Jennifer Lien, who portrayed Kes during the first three seasons of the show. At the end of the season, co-creator and executive producer Jeri Taylor retired.

With the addition of Seven, a series of episodes focused on her backstory and relationship with other characters. The season opened with a Nielsen rating of 8.8% for "Scorpion", which was higher than any episode since the pilot. "Unforgettable" received the lowest rating with 3.4%.

The fanbase initially responded negatively to Ryan's addition to the cast, raising concerns over Seven's sexual attractiveness, which had the potential to overshadow the story. But following the airing of the episodes, critics applauded Ryan's acting skills and her role as Seven, noting that it would improve the quality of the stories and the series itself. Acclaimed episodes like "Scorpion", "Year of Hell", and "Hope and Fear", led critics to describe the fourth season as one of the best. The episode "Living Witness", directed by Tim Russ, received special critical accommodation as one of the best episodes of the entire series.
