Angel Stadium of Anaheim (originally Anaheim Stadium and later Edison International Field of Anaheim) is a modern-style ballpark located in Anaheim, California. It is the home ballpark to Major League Baseball's Los Angeles Angels of Anaheim of the American League, and was previously home to the NFL's Los Angeles Rams (now St. Louis Rams). The stadium is often referred to by its unofficial nickname The Big A.

Angel Stadium and its surrounding parking lot are roughly bounded by Katella Avenue to the north, the Orange Freeway to the east, Orangewood Avenue to the south, and State College Boulevard to the west. Located near the eastern boundary of the parking lot is the landmark "Big A" sign and electronic marquee, which originally served as a scoreboard support. The halo located near the top of the 230' tall, 210-ton sign is illuminated following games in which the Angels win (both at home and on the road), which gives rise to the fan expression, "Light up the Halo!"

To the north, a train station servicing Metrolink's Orange County Line and Amtrak's Pacific Surfliner, is located on the edge of the stadium's parking lot. The station provides convenient access to the stadium, the nearby Honda Center, and Disneyland from various communities along the route, which links San Luis Obispo, Los Angeles, and San Diego. The track is owned by the Orange County Transportation Authority.

Aside from professional baseball and football, Angel Stadium has hosted high school and college football games, National Football League pre-season games, the short-lived World Football League, two crusades by evangelist Billy Graham, nearly twenty consecutive annual crusades by evangelist Greg Laurie and musical concerts featuring such acts as The Rolling Stones, The Who, and Pink Floyd.

Angel Stadium, the fourth oldest active Major League Baseball stadium, was selected to host the 2010 Major League Baseball All-Star Game.

The stadium also houses the studios and offices of the Angels' owned and operated flagship radio station, KLAA (830 AM).

Angel Stadium has been the home of the Angels since their move from Los Angeles. In 1964, ground was broken for Anaheim Stadium and in 1966, the then-California Angels moved into their new home after having spent four seasons renting Dodger Stadium (referred to during Angels games as Chávez Ravine Stadium) from the Dodgers.

The stadium was built on a parcel of about 160 acres (0.65 km2) of flat land originally used for agricultural purposes by the Allec, Russell, and Knutzen families in the southeast portion of Anaheim. Consistent with many major-league sports stadiums built in the 1960s, it is located in a suburban area, though one that is host to major tourist attractions.

The field dimensions (333 feet instead of 330, for example) were derived from a scientific study conducted by the Angels. Based on the air density at normal game times (1:30 pm and 8 pm), the Angels tried to formulate dimensions that were fairly balanced between pitcher, hitter and average weather conditions. The Angels tinkered with those dimensions several times, expanding or contracting parts of the outfield by a few feet here and there, to try to refine that balance.

None of this seemed to matter to their Hall of Fame pitcher Nolan Ryan, who threw four of his record seven no-hitters in this ballpark, and racked up 2,416 of his 5,714 career strikeouts in eight seasons with the Angels (Ryan stats from The Sporting News Baseball Record Book). One of the no-hitters, on June 1, 1975, was his fourth, which tied Sandy Koufax's career record, one Ryan would eventually supplant.
