2024 San Francisco 49ers season

The 2024 season was the San Francisco 49ers' 75th in the National Football League (NFL), their 79th overall, their eleventh playing their home games at Levi's Stadium and their eighth under the head coach/general manager tandem of Kyle Shanahan and John Lynch. It was also the first with CEO Jed York as principal owner; after serving as operating head of the franchise since 2008, he acquired enough equity from his mother, co-chairwoman Denise DeBartolo York, to become principal owner. DeBartolo York and her husband, John York, remained co-chairs.

The 49ers entered the season as defending NFC Champions. However, the team went on to lose seven of their final eight games, failing to improve on their 12–5 record from 2023. A Week 11 home loss to their division rival Seattle Seahawks, 20–17, followed by back-to-back road blowout losses (a Week 12 loss to their rival Green Bay Packers, 38–10 and a 35–10 loss to the Buffalo Bills on a snowy Sunday night in Week 13.), highlighted their midseason decline. With wins by the Los Angeles Rams and Washington Commanders in Week 16, the 49ers were officially eliminated from playoff contention for the first time since 2020. Later that day, a loss to the Miami Dolphins confirmed the franchise’s first losing season since that year. Overall, their 6–11 record was the worst for a team coming off a Super Bowl loss since the 2003 Oakland Raiders went 4–12.

The team was heavily impacted by injuries to key starters throughout the season. Christian McCaffrey, Brandon Aiyuk, Jordan Mason, Trent Williams, and Mitch Wishnowsky, among others, were placed on injured reserve and missed the remainder of the season. McCaffrey had suffered an Achilles injury that caused him to miss the first eight games. Due in large part to these injuries, several members of the 2024 rookie draft class saw significant playing time, including wide receiver Ricky Pearsall, offensive guard Dominick Puni, and defensive backs Renardo Green and Malik Mustapha. The 49ers' defense struggled under defensive coordinator Nick Sorensen, finishing 29th in points allowed and recording only two takeaways following their bye week. Sorensen was subsequently relieved of his duties following the season. Special teams coordinator Brian Schneider was also dismissed after the season due to continued struggles in the kicking game.
