Municipal Stadium was a stadium in Hagerstown, Maryland, United States. It was primarily used for baseball and was built in 1930 in a short time period of six weeks and had a capacity of 4,600 people. The ballpark was demolished in Spring 2022.

From 1915 to 1929, Hagerstown's minor league team played at Willow Lane Park, where Bester Elementary School is now located. When the city made the decision to build the school, the need for a new stadium was urgent. The Field and Athletic Association was created to find land and build a stadium. The organization struck a deal with the city, leasing a tract of land for 99 years at $1 per year. Municipal Stadium was quickly built on the land in a mere six weeks, just in time for the first home game on May 8, 1930. Since then, the stadium has undergone two major renovations.

Hagerstown's Municipal Stadium hosted several games featuring Negro league teams during the first decade and a half of its existence. Among the Negro league teams that played in Hagerstown were the Indianapolis Clowns, Homestead Grays and the Pittsburgh Crawfords.

From 1941 to 1949, the Hagerstown Owls played in the Class B Interstate League and called Hagerstown's Municipal Stadium home. In 1950, the Hagerstown entry in the Class B Interstate League was sold and was renamed the Hagerstown Braves. The Hagerstown Braves remained in existence from the 1950 season through the 1953 season. The Braves won one championship with the Interstate League in 1952.

A major renovation took place in 1981, when Minor League Baseball returned to Hagerstown after a 26-year absence from the city. About $546,000 was put into the stadium overhaul, which included the installation of a public address system, stadium lights, underground electricity, and new seats and bleachers. In 1995, $500,000 worth of improvements to the stadium were made, such as the installation of new seats, and upgrading the VIP section to include cup holders. The Sunset Grille and bar area was also added at this time.

In 1990, sitting president, George H. W. Bush enjoyed a Hagerstown Suns game at Municipal Stadium. Although he later visited the Frederick Keys for two games at their stadium, the visit to the Suns game was the first presidential visit for a minor league baseball team.

In 2005, a movement arose to rename an adjacent street to honor Willie Mays, who played his first game at the park as a minor league rookie. The proposal, however, was shot down due to protests by various American war veterans groups who wanted to keep the original road name of Memorial Boulevard.

The playing surface was renovated following the 2010 season. In addition, seating improvements and the installation of a state-of-the-art video board enhanced the fans experience in 2011. In April 2014, Hagerstown and the Suns agreed to a two-season lease extension on Municipal Stadium for 2015 and 2016 which could be voided by mutual agreement.

Municipal Stadium was one of the three oldest Minor League baseball stadiums in the country when the Hagerstown Suns were disbanded in 2020.

Prior to the 2021 season, the semi-professional Hagerstown Braves (not to be confused with the former minor league team of the same name that played at Municipal Stadium in the early 1950s) announced they would return to play their 2021 season at Municipal Stadium.

On March 24, 2022, the Hagerstown City Council voted 5–0 to proceed with the demolition of Municipal Stadium. As part of the demolition effort, more than 60 bidders attended an auction of stadium seats.
