The 2018 season was the San Francisco 49ers' 69th in the National Football League, their 73rd overall, their fifth playing their home games at Levi's Stadium and their second under the head coach/general manager tandem of Kyle Shanahan and John Lynch.
After finishing 6-10 from a 0-9 start in the previous year, the 49ers were looking to improve from that record and make the playoffs for the first time since 2013. However, the 49ers' season ended with a record of 4-12 and were plagued by multiple season-ending injuries, which have included RB Jerick McKinnon tearing his ACL in training camp and QB Jimmy Garoppolo also tearing his ACL in Week 3 against the Kansas City Chiefs. The 49ers were eliminated from playoff contention following a Week 13 loss to the Seattle Seahawks. In Week 15, however, the 49ers upset the Seahawks 26-23 in overtime at home, snapping the 49ers' 10-game losing streak to them that dated back to 2013 Playoffs. The win also stopped the Seahawks from clinching a playoff spot that week. The 49ers failed to improve on their 6-10 record from last year. The 49ers also went 0-8 on the road for the first time since 1979.
The 49ers defense would also go on to set multiple NFL records for futility. During the entire 16 game schedule of the 2018 NFL season, the 49ers defense would accumulate just two interceptions, breaking the previous mark of three. Incredibly, that included strike shortened NFL seasons. Putting that into perspective, a total of 40 different players throughout the league would go on to have more interceptions than the entire 49ers team. The 49ers would also have just seven total takeaways on the season, smashing the previous record of 11. The 49ers were also last in the league with a -25 turnover differential, the worst mark since 2008.
The 2018 49ers would go on to set one more notable "futility" mark after the team went 8-0 to start the following season, thus giving the 2018 49ers the worst record in NFL history of any team that went on to go undefeated that far into the following season.

Three interceptions by Jimmy Garoppolo, who earned his first loss as an NFL starter, would hurt the 49ers in the end. The 49ers lost 24-16, with the difference being a Garoppolo pick-six as well several key drops by receivers.
Despite the Lions' attempted comeback in the fourth quarter, the 49ers would hang on to win 30-27 as the team earns their first win of the season behind 2 TDs from Garoppolo and Matt Breida's 138 yards rushing.
Not only did the 49ers lose the game, Jimmy Garoppolo got carted off in the fourth quarter with a serious knee injury. The next day, an MRI further revealed that Garoppolo had torn his ACL, ruling him out for the rest of the season.
These two teams would meet again the following season in Super Bowl LIV, with the 49ers falling short 31-20.
The first post-Garoppolo game of the season was a surprisingly competitive game, mostly due to safety Antone Exum getting a pick-six in the first quarter, but the 49ers still lost 29-27 and dropped to 1-3 on the season and 0-1 after Garoppolo's injury.
Playing a winless Cardinals team desperately seeking a win, the 49ers held rookie QB Josh Rosen in check, but were hurt by five offensive turnovers, one of which resulted in a defensive touchdown for Arizona. The 49ers drop to 1-4 (0-2 since Garoppolo's injury) heading into a Monday Night road game against the Packers.
The 49ers held a 30-23 lead in the final three minutes, but Aaron Rodgers threw a touchdown pass to Davante Adams to tie the game with less than 2 minutes left. On the 49ers' next drive, a critical C.J. Beathard interception plus an illegal contact penalty on Richard Sherman in the final minute led to a 27-yard game-winning field goal by Mason Crosby to send the 49ers to a 33-30 loss and a 1-5 record heading into next week's home game against the undefeated Rams.
With the loss, the Niners dropped to 1-7 and last place in the NFC West. They were also swept by the Cardinals for the 4th consecutive year.
This was the first start for Nick Mullens at QB, who replaced C.J. Beathard. The game was incredibly one-sided, with the 49ers winning by over 30 points.
This was the first time since 2013 that the 49ers beat the Seahawks, snapping a 10-game losing streak which dates back to the 2013-14 NFC Championship Game. This also prevented the Seahawks from clinching a Wild-Card Berth that week.
With the loss, the 49ers finished 0-8 on the road for the first time since 1979.
