List of episodes

The fourth season of the American science fiction television series Star Trek: Enterprise commenced airing on the UPN network in the United States on October 8, 2004 and concluded on May 13, 2005 after airing 22 episodes. Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. The fourth season saw changes made to the production team, with Manny Coto becoming the show runner. He had joined the team during the third season as a co-executive producer. Other changes included Star Trek novelists Judith and Garfield Reeves-Stevens being brought on board as writers.

Season four was the final season of the series, with the show being cancelled during the filming of the episode "In A Mirror, Darkly". Following the cancellation, fans of the show conducted protests and raised funds to pay for a fifth season, however their efforts were unsuccessful. "These Are The Voyages..." was the final episode of the series, and gained the highest number of viewers for the season according to Nielsen Media Research. Despite critics describing the fourth season in a warmer manner, the finale was received poorly, with Rick Berman later regretting the storyline. The series was nominated for three Emmy Awards for episodes in the fourth season, but the only award won was an Outstanding Visual Effects for a Broadcast Series at the 2005 Visual Effects Society awards.
