The 2006 Oakland Raiders season, which was supposed to improve on a lackluster 4–12 record from 2005, ended with the Raiders suffering through a 2–14 campaign, the worst record in the 2006 NFL season, the worst season since the club went 1–13 in 1962 and their worst since the National Football League went to a 16-game schedule in 1978, thus earning the right to the No. 1 pick in the 2007 NFL Draft. Since losing to the Tampa Bay Buccaneers in Super Bowl XXXVII, the Raiders have a four-year aggregate record of 15–49, the worst in the NFL over that span.
