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. Season four was the final season of the series; despite critics describing the fourth season in a warmer manner than those prior, 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.
