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 being 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.

They entered the season as defending NFC Champions. Already struggling with a 5–4 start to the season, the 49ers went on to lose seven of their eight remaining games and failed to improve on their 12–5 record from 2023 with a Week 11 loss to the Seattle Seahawks and failed to match it after a Week 12 loss to their rival Green Bay Packers. With the Los Angeles Rams and Washington Commanders winning in Week 16, the 49ers were eliminated from playoff contention for the first time since 2020. The 49ers would subsequently suffer their first losing season since that year when they lost to the Miami Dolphins later that day. Overall, their 6–11 record was the worst for a team coming off a Super Bowl loss since the 2003 Oakland Raiders.

The team struggled with injuries to their starters throughout the season. Christian McCaffrey, Brandon Aiyuk, Jordan Mason, Trent Williams, and Mitch Wishnowsky, among other players, were relegated to 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, members of the team's rookie draft class saw significant playing time, among them 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. Following the season, Sorensen was relieved of his role. Special teams coordinator Brian Schneider was also relieved of his duties after the season due to immense struggles in the kicking game during the season.
