City Connect is a brand name for a line of alternate uniforms made by Nike, Inc. for Major League Baseball (MLB) teams. The uniforms feature different color schemes, typefaces, and graphic elements compared with the teams' typical home and away uniforms. The uniforms are designed to reflect the cultural aspects of each team's home city. According to the agreement, teams may rotate in a new jersey after three years to debut a new look.
Of the MLB's 30 teams, 27 have a City Connect uniform. The New York Yankees (who traditionally do not wear an alternate uniform), the Athletics (who are not officially associated with any city during their planned relocation to Las Vegas), and the Chicago Cubs (whose Wrigleyville City Connect uniform was discontinued after the 2024 season and replaced with a “Chicago Blues” alternative uniform, which is not part of the City Connect Program). are the only three teams without a City Connect uniform.
While MLB has no rule restricting teams from wearing City Connect uniforms during postseason play, to date no team has worn their City Connect uniforms during any postseason round, including the World Series.
Teams Nike and MLB introduced the first round of City Connect uniforms during the 2021 season for seven teams, (Red Sox, Marlins, White Sox, Cubs, Diamondbacks, Giants, Dodgers). A second round debuted during the 2022 season for another seven teams (Nationals, Astros, Royals, Rockies, Angels, Brewers, Padres), a third during the 2023 season for six teams (Braves, Rangers, Mariners, Reds, Orioles, Pirates), and a fourth during the 2024 season for nine teams (Phillies, Mets, Rays, Tigers, Guardians, Cardinals, Blue Jays, Twins, Dodgers).
