Phoenix Municipal Stadium, baseball stadium, located in Phoenix, Arizona

Phoenix Municipal Stadium is a baseball stadium in Papago Park in Phoenix, Arizona, with a listed capacity of 8,775. It has an open-air grandstand, enclosed press box facilities added in a 2003 renovation, and outfield dimensions that honor ASU players Brock and Hahn. The stadium is 2.5 miles from Arizona State University's main campus in Tempe.

The city council approved a new stadium at Papago Park on June 4, 1962, and it opened on March 8, 1964, when the Giants beat Cleveland 6–2 before 8,582 fans; Willie Mays hit the park's first home run. The Giants trained here through 1981, the Oakland Athletics from 1982 to 2014, and Arizona State University's Sun Devils moved in for the 2015 season under a 25-year lease.

The outfield dimensions honor two figures in Arizona State baseball history, the Brock and Hahn lines. Arizona State played occasional games here in the 1960s, notably against rival Arizona, before Reggie Jackson became the first college player to hit a home run out of the stadium.

The stadium sits in Papago Park, about 2.5 miles from Arizona State's main campus in Tempe, and the Phoenix light rail system serves the area. The 2003 renovation added enclosed press box facilities, new dugouts, and concourse areas with benches, shading, and a historical timeline. Several Arizona high school baseball championships are decided there in early May.

The stadium's light poles were installed at the Polo Grounds in New York City in 1940 and served there until that ballpark was demolished in 1964. Giants owner Horace Stoneham then shipped them to Phoenix, so the fixtures predate the stadium itself.
