The
MLB London Series is an arrangement for Major League Baseball (MLB) to play select regular season games at London Stadium in London, England. The arrangement was initially for two years, 2019 and 2020, which was sponsored by Mitel and branded as
Mitel & MLB Present London Series. The 2019 games were the first MLB contests ever played in Europe, and featured the Boston Red Sox hosting two games against the New York Yankees. Two games planned for 2020 between the St. Louis Cardinals and Chicago Cubs were cancelled due to the COVID-19 pandemic. In 2022, the arrangement between MLB and Greater London was renewed for games in 2023, 2024 and 2026. Beginning with the 2023 season, the series is branded as the
MLB World Tour: London Series, reflecting the new "MLB World Tour" name applied to games played outside the U.S. and Canada.
