2005 Oakland Raiders season

The 2005 Oakland Raiders season was their 46th in the league. They were unable to improve upon their previous season's output of 5–11, instead only going 4–12. The team finished the season on a six-game losing streak. The Raiders team were tied with the San Francisco 49ers, the Green Bay Packers, the New York Jets, and the Tennessee Titans where they got 4-12.

The Raiders acquired Randy Moss from the Minnesota Vikings in a trade for linebacker Napoleon Harris and a first-round draft pick. The acquisition of Moss sought to help with the team's struggling receiving corps for the past two years. However, Moss struggled in his first season with the Raiders, and he finished the season with only 60 receptions.
