The 2015 Chicago Cubs season was the 144th season for the franchise, the 140th in the National League and the 100th at Wrigley Field. The Cubs were managed by Joe Maddon in his first year as Cubs manager and played their home games at Wrigley Field as members of the National League Central.

Wrigley Field is a baseball stadium on the North Side of Chicago, Illinois. It is the ballpark of Major League Baseball's Chicago Cubs, one of the city's two MLB franchises. It first opened in 1914 as Weeghman Park for Charles Weeghman's Chicago Whales of the Federal League, which folded after the 1915 baseball season. The Cubs played their first home game at the park on April 20, 1916, defeating the Cincinnati Reds 7–6 in 11 innings. Chewing gum magnate William Wrigley Jr. of the Wrigley Company acquired the Cubs in 1921. It was named Cubs Park from 1920 to 1926, before being renamed Wrigley Field in 1927. The stadium currently seats 41,649 people and is the second stadium to be named Wrigley Field, as a Los Angeles ballpark with the same name opened in 1925.
