Only two teams failed to complete the entire 162-game regular season schedule, as the game between the Baltimore Orioles and the New York Yankees at Yankee Stadium on September 27 was canceled due to rain and never made up, owing to scheduling constraints and the game being inconsequential to the playoffs. It would be the first time since that some teams played more regular season games than the others.

Schedule Major League Baseball released its 2026 schedule on August 26, 2025. Each team will play 162 regular-season games. As has been the case since 2025, each team was scheduled to play 13 games against their division rivals, totaling 52 games. Each team would play six games against eight opponents and seven games against two opponents in the same league for a total of 62 games. Each team would also play 48 interleague games, including a six-game home-and-home series against their designated interleague rival.

The regular season started on March 25, with a standalone night game featuring the San Francisco Giants hosting the New York Yankees. The slate of Opening Day games then took place on March 26, the earliest that it has been scheduled in MLB history. This season's "Rivalry Weekend" is planned on May 15–17, again 11 series featuring prime "interleague" rivals and the matches reversed from the previous year.

The MLB Mexico City Series returned when the Arizona Diamondbacks and the San Diego Padres played a two-game series at Alfredo Harp Helú Stadium in Mexico City on April 25–26. The scheduled return of the London Series was cancelled due to scheduling conflicts at London Stadium and Fox's availability due to the 2026 FIFA World Cup. The World Cup also affected schedules of the Kansas City Royals, Philadelphia Phillies, Seattle Mariners, and Texas Rangers, whose home stadiums are located near World Cup venues.

The 96th All-Star Game was played on July 14 at Citizens Bank Park in Philadelphia, Pennsylvania, the home of the Philadelphia Phillies. The game was part of the celebration of the 250th anniversary of the signing of the United States Declaration of Independence.

The MLB at Field of Dreams game returned on August 13 after a three-season absence, with the Minnesota Twins hosting the Philadelphia Phillies. The MLB Little League Classic at Bowman Field in Williamsport, Pennsylvania, was played on August 23 between the Atlanta Braves and the Milwaukee Brewers.

A Subway Series matchup between the New York Mets and the New York Yankees was played at Yankee Stadium on September 11–13 to mark the 25th anniversary of the September 11 attacks. The two teams squared off at Citi Field for the 20th anniversary.

Rule changes On September 23, 2025, MLB's competition committee approved use of the Automated Ball-Strike System (ABS) beginning with the 2026 season. Batters, pitchers, and catchers are allowed to request challenges by tapping on their helmet or cap. Each team starts with two challenges, retains a challenge if it is successful, and receives additional challenges in extra innings, if the team is out of challenges during regulation.
