Which baseball stadium, opened in 1912, is the oldest active ballpark in Major League Baseball?

Fenway Park is the answer. Home of the Boston Red Sox, Fenway Park opened in Boston’s Fenway neighborhood in 1912 and remains the oldest active ballpark in Major League Baseball, with its early-20th-century design and famous Green Monster left-field wall making it one of the sport’s most distinctive stadiums.

Fenway Park and the Boston Red Sox

Fenway Park is the longtime home of the Boston Red Sox. Its identity is closely tied to the team, the city of Boston, and Major League Baseball’s older ballpark era. Unlike many early stadiums that were replaced, Fenway has remained in active MLB use while keeping many of the unusual features that came from its original urban setting.

Opened in 1912

Fenway Park opened in 1912, making it the oldest active ballpark in Major League Baseball. That date places it ahead of Wrigley Field, which opened later in 1914. Fenway’s continued use gives it a direct connection between early-20th-century baseball and the modern MLB schedule.

The Green Monster and Unusual Dimensions

The Green Monster is Fenway Park’s famous tall wall in left field. It is one of the most recognizable stadium features in baseball because it affects how balls are hit, fielded, and scored at the park. Fenway’s unusual dimensions reflect older ballpark design, where the shape of the surrounding city helped define the playing field.

Why Fenway Is Still Active

Fenway Park remains active because it has been preserved, renovated, and adapted while continuing to host Red Sox home games. Its age is part of its significance, but its ongoing use is what makes the “oldest active ballpark” title accurate. The stadium’s combination of history, distinctive dimensions, and modern operation keeps Fenway central to baseball history.
