2018 Oakland Raiders season

The 2018 season was the Oakland Raiders' 49th in the National Football League (NFL), their 59th overall, their 24th since their return to Oakland, and their first under head coach Jon Gruden since his rehiring by the organization (fifth overall). The Raiders finished the season with a 4–12 record, failing to improve upon their previous season's record of 6–10, and their worst since 2014.

With a loss to the Kansas City Chiefs in Week 13, the Raiders were eliminated from playoff contention for the second consecutive season. With their week 15 loss to the Bengals, the Raiders failed to improve their record from the previous season. The loss also secured their spot at last in the AFC West.

On December 10, the Raiders fired general manager Reggie McKenzie who had been with the Raiders since 2012.

This was the first time since 1999 that Sebastian Janikowski was not on the opening day roster.

Stadium issues
Although the league approved the Raiders' eventual relocation to Las Vegas on March 27, 2017, the team maintained its lease at the Oakland–Alameda County Coliseum and used the stadium for the 2018 season while the team's new stadium in Las Vegas was under construction. Initially in April 2017, the operators of the Coliseum stated they would be unwilling to sign a lease extension for the team to play at the stadium while their new venue in Las Vegas was being built; however by September of that year, the Coliseum operators expressed willingness to negotiate, but insisted on concessions to compensate for the million-dollar deficit the Coliseum runs by hosting Raiders games. Owner Mark Davis stated he preferred to stay in Oakland for the 2019 season but was considering other options, including Las Vegas's Sam Boyd Stadium, Berkeley's California Memorial Stadium, Mackay Stadium in Reno, Nevada; the San Francisco 49ers's Levi's Stadium and even the Alamodome in San Antonio, Texas, a venue thought to have been ruled out in 2014. Davis acknowledged that if fans failed to support the team similarly to the 1996 Houston Oilers, it could hasten the relocation. Team management also indicated they would relocate after 2018 if there were any lawsuits filed against the team; the city of Oakland sued the Raiders and all other teams in the league on December 11, 2018, however the Raiders remained in Oakland for the final year despite the lawsuit.

Coaching changes
On January 6, 2018, the Raiders hired their former head coach, Jon Gruden, who returned to the Raiders and coaching from ESPN's Monday Night Football. Gruden received a 10-year, $100-million contract to return to the Raiders. Gruden last coached in the NFL in 2008 with the Tampa Bay Buccaneers and last coached the Raiders in 2001. At the press conference announcing the hiring of Gruden on January 9, Gruden announced that Los Angeles Rams quarterbacks coach Greg Olson had been hired as offensive coordinator, though Gruden would call plays, while former Cincinnati Bengals defensive coordinator Paul Guenther was hired as the new defensive coordinator. Gruden also announced that former Tampa Bay Buccaneers and Dallas Cowboys special teams coordinator Rich Bisaccia was hired to serve as special teams coordinator. On January 29, the Raiders named Brian Callahan, son of their former head coach Bill Callahan, as the new quarterbacks coach.

Khalil Mack holdout and trade to Chicago
On September 1, 2018, the Raiders traded defensive star Khalil Mack along with their 2020 2nd round pick to the Chicago Bears for two first round picks (RB Josh Jacobs and CB Damon Arnette), a 2019 6th round pick, and a 2020 3rd round pick, after he had held out of training camp.
