Wrigley Field is a baseball stadium in Chicago, Illinois, United States that has served as the home ballpark of the Chicago Cubs since 1916. It was built in 1914 as Weeghman Park for the Chicago Federal League baseball team, the Chicago Whales. It was also the home of the Chicago Bears of the National Football League from 1921-1970. It was also called Cubs Park from 1920 to 1926 before finally being renamed for then Cubs team owner and chewing gum industrialist William Wrigley Jr..

Located in the residential neighborhood of Lakeview, Wrigley Field sits on an irregular block bounded by Clark and Addison Streets and Waveland and Sheffield Avenues. The area surrounding the ballpark contains bars, restaurants and other establishments and is typically referred to as Wrigleyville. The ballpark's mailing address, as many fans of the movie The Blues Brothers know, is 1060 W. Addison Street. During Cubs games, fans will often stand outside the park on Waveland Avenue, waiting for home run balls hit over the wall and out of the park. (However, as a tradition, Cubs fans inside and sometimes even outside the park will promptly throw any home run ball hit by an opposing player back onto the field of play, a ritual depicted in the 1977 stage play, Bleacher Bums, and in the 1993 film, Rookie of the Year.)

Wrigley Field is nicknamed The Friendly Confines, a phrase popularized by "Mr. Cub", Hall of Famer Ernie Banks. Since 2006, its capacity has been 41,118, making Wrigley Field the fourth-smallest and most actively used ballpark in 2006. It is the second oldest active major league ballpark (behind Fenway Park), and the only remaining Federal League park. When opened in 1914, Wrigley Field had a seating capacity of 14,000 and cost $250,000 to build.
