Nelson W. Wolff Municipal Stadium, Baseball stadium in San Antonio, United States.

Nelson W. Wolff Municipal Stadium is a ballpark in San Antonio, Texas, opened on April 18, 1994, with 6,200 fixed seats and a grass berm in left field that holds about 3,000. Its outfield dimensions are 310 feet to left, 402 to center and 340 to right. Behind home plate, two large brick bell towers echo the old Mission Stadium.

The stadium opened in 1994 and quickly became home to the San Antonio Missions baseball team. Over time, it has also hosted the UTSA Roadrunners, establishing itself as a key venue for the region's baseball activities.

The Missions hold "Military Night" games, inviting recently graduated troops from nearby Lackland Air Force Base to Friday games; planes can often be seen behind the outfield wall. The stadium is named for Bexar County Judge Nelson Wolff, a former Texas legislator and San Antonio councilman and mayor. In April 2021 it was announced as the site of two Mexican League exhibition games, between the Tecolotes de los Dos Laredos and the Acereros de Monclova.

The stadium sits about 8 miles (13 km) west of downtown San Antonio. A concourse wraps around the playing field, and the back six rows of Infield Reserved sections 200–208 are shaded; no poles block the view. The left-field grass berm holds about 3,000 people, so arrive early for popular games.

The two brick bell towers at the entrance echo a feature of the old Mission Stadium, the Missions' earlier home. Behind the outfield wall, planes can often be seen landing at and taking off from Lackland Air Force Base, and the club holds Military Night for recently graduated troops at Friday games.
