The 2023 season was the San Francisco 49ers' 74th in the National Football League (NFL), their 78th overall, their tenth playing their home games at Levi's Stadium and their seventh under the head coach/general manager tandem of Kyle Shanahan and John Lynch. This was the team's first season since 2013 and 2016, respectively, without safety Jimmie Ward and quarterback Jimmy Garoppolo on the roster; Garoppolo signed with the Las Vegas Raiders on March 17, while Ward signed with the Houston Texans the following day.

The team had a 5–0 start that left them, along with the Philadelphia Eagles, as the last undefeated teams remaining. The 49ers lost to the Cleveland Browns in Week 6, their first of three consecutive losses heading into their bye week. Following the bye, the 49ers won 6 games in a row and, with a week 14 win over the division rival Seattle Seahawks, coupled with the Green Bay Packers' loss to the New York Giants on Monday Night Football, became the first team to clinch a playoff berth in 2023, their fourth in five seasons. The following week the 49ers clinched the NFC West in consecutive seasons for the first time since 2011–2012 with a 45–29 win over the Arizona Cardinals. With a 27–10 Week 17 win over the Washington Commanders, and the Detroit Lions and Philadelphia Eagles losing, the 49ers clinched home-field advantage throughout the NFC playoffs for the first time since 2019. Despite clinching the number one seed, the team failed to match their 13–4 record from the previous year, going 12–5, following their season finale loss to the Los Angeles Rams. After a close 24–21 win in the divisional playoffs against the Green Bay Packers, the 49ers advanced to the NFC Championship Game for the 19th time overall, hosted their record 11th NFC Championship Game, the fourth time in five seasons, the fourth time they had made it in three consecutive seasons, after 1988–1990, 1992–1994, and 2011–2013. In the NFC Championship game against the Detroit Lions, the 49ers came back from a 24–7 halftime deficit to win 34–31, setting an NFL record for overcoming the largest halftime deficit in a championship game. Coincidentally, the 49ers had been the most recent team to overcome a 17-point deficit in a championship game (but which was not a halftime deficit), which happened in 2012 against the Atlanta Falcons. The win allowed the 49ers to make their second Super Bowl appearance in 5 seasons, and their eighth appearance overall. The 49ers faced the Kansas City Chiefs in Super Bowl LVIII, which was a rematch of Super Bowl LIV. However, they were once again defeated by the Chiefs by a final score of 25-22 in overtime, failing to win the Super Bowl for the first time since 1994.

The 49ers finished the season in the top 10 in multiple offensive and defensive categories. On offense, the 49ers finished with 491 points scored, which was third most in the league and the second most points scored in franchise history (behind the 1994 team which scored 505 points). They finished second in the league in total offense with 398.4 yards per game, which included finishing fourth in pass yards per game (257.9) and third in rush yards per game (140.5). They also established an NFL record by becoming the first team in league history to have four players with over 1,000 scrimmage yards, with Deebo Samuel (1,085), George Kittle (1,022), Christian McCaffrey (2,023) and Brandon Aiyuk (1,317) all surpassing the mark. On defense, the 49ers finished third in the league in scoring defense, giving up just 17.5 points per game and finished first in the league with 22 interceptions (tied with the Chicago Bears).

Not only were eight of the 49ers' 12 victories against teams that finished with a winning record, they also defeated every team that made the playoffs in their conference, the first time this has happened since 1993 by the Chiefs. The 49ers defeated the Rams, Cowboys, Buccaneers, and Eagles in the regular season, while defeating the Packers and Lions in the playoffs.

The San Francisco 49ers drew an average home attendance of 71,655 in 8 home games in the 2023 NFL season.
