The following is the 2004–05 network television schedule for the six major English language commercial broadcast networks in the United States. The schedule covers primetime hours from September 2004 through May 2005. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 2003–04 season. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football.
Beginning this season, the major networks were no longer producing original dramatic content for Saturday broadcast (an exception being ABC's The Wonderful World of Disney, although it often featured rebroadcast material). Saturday schedules consisted instead of nonfiction reality-based programming and rebroadcasts of dramatic series episodes from earlier in the week.
New series are highlighted in bold.
