The following is the 2005–06 network television schedule for the six major English language commercial broadcast networks in the United States. The schedule covers primetime hours from September 2005 through May 2006. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 2004–05 season. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football.
This would be the final season of broadcasting for both UPN and The WB. They would merge to form The CW next season. The famous Monday Night Football would move to ESPN from ABC after the 2005 NFL season ended with Super Bowl XL
New series are highlighted in bold.
Each of the 30 highest-rated shows is listed with its rank and rating as determined by Nielsen Media Research.
PBS, the Public Broadcasting Service, was in operation, but is not included because the schedule was set by each local station.
From February 10 to 26, 2006, all of NBC's primetime programming was preempted in favor of coverage of the 2006 Winter Olympics in Turin.
