Alamo Stadium, Football stadium in Monte Vista Historic District, San Antonio, United States.

Alamo Stadium is a horseshoe-shaped football and soccer ground in San Antonio's Monte Vista Historic District, built of rough-hewn tan and light gray limestone on the site of an abandoned rock quarry. Its seating capacity is 18,500, and the front facade carries the words "SAN ANTONIO PUBLIC SCHOOLS" and "ALAMO STADIUM" in blue capital letters above five round windows and three stone pillars.

Alamo Stadium was proposed by SAISD trustees in May 1939 and built on the site of an abandoned rock quarry, completed in September 1940 as a Works Progress Administration project (65-1-66-30). The cost was just under $500,000, with about $110,000 from district revenue bonds. Its opening on September 20, 1940, a high school football doubleheader, drew 24,000 people. It was listed on the National Register of Historic Places on September 8, 2011.

The stadium's nickname, "The Rock Pile", comes from its limestone construction. Since 1940 it has hosted the annual Chili Bowl between Fox Tech and Lanier high schools, which regularly sold out and averaged about 23,000 spectators until Fox Tech's team was disbanded after the 2009 season. The Battle of the Bands is held there each year during Fiesta.

The stadium sits in the Monte Vista Historic District, and parking is limited, especially on its east side, with little room to expand. Track meets hosted by SAISD, including the Region IV-5A meets in late April or early May, also draw crowds. The Battle of the Bands takes place here each year during Fiesta.

The stadium's nickname, "The Rock Pile", comes from its limestone construction on the site of an abandoned rock quarry. The 1940 opening drew 24,000 spectators to a high school football doubleheader: Corpus Christi beat Jefferson 14-0, then Brackenridge beat Houston Reagan 19-2.
