The San Francisco 49ers' 2026 regular season opponents are already locked in, and while fans eagerly await the official NFL schedule release, a few matchups stand out as must-watch events. For this preview, we'll set aside the NFC West divisional clashes and focus on three games that promise high drama, history, and intensity.
First, the 49ers' trip to face the Kansas City Chiefs is loaded with unfinished business. Under head coach Kyle Shanahan, San Francisco has yet to beat Patrick Mahomes and the Chiefs. The last time they visited Arrowhead Stadium, in 2018, Jimmy Garoppolo tore his ACL in a Week 2 loss, a defeat that spiraled into a losing season and ultimately landed the 49ers the No. 2 draft pick—used to select Nick Bosa. While a regular-season win won't erase the sting of two Super Bowl losses to Kansas City, it would be a powerful statement. Beating the "big, bad wolf" on the road would signal that this 49ers squad can finally conquer its nemesis, adding a layer of redemption to an already fierce rivalry.
Next, the Philadelphia Eagles matchup carries a charged history. Since the 2022 NFC Championship Game, where the Eagles emerged victorious, the two franchises have developed a chippy rivalry. Philadelphia went on to win a Super Bowl that season, but the 49ers have since taken two straight wins, including a Wild Card playoff victory in Philadelphia last year. In 2026, the Eagles will debut a new playcaller and an offensive scheme that reportedly mirrors Shanahan's own system—adding a fascinating tactical subplot. Expect both teams to come out swinging, and with national TV appeal, this could be one of the season's most-watched games.
Finally, the 49ers' road game against the Los Angeles Chargers is more than just a California clash. After being denied a visit to SoFi Stadium in recent years, San Francisco fans will likely flood the venue in a sea of red. But the real headline is the reunion of Jim Harbaugh and the 49ers. For the first time since taking over as Chargers head coach, Harbaugh—who led San Francisco to a Super Bowl appearance and three NFC title games—will face his original NFL team. The emotional weight, the coaching chess match, and the fan takeover make this a can't-miss event, packed with storylines that will resonate long before kickoff.
