Mirowski Park in Warsaw, Municipal park in Śródmieście, Poland.

Mirowski Park is an urban green space in Srodmiescie occupying a rectangular plot between Jana Pawla II Avenue and Marszalkowska Street. Walking paths crisscross the grounds, offering residents and visitors access to trees and open areas throughout the park.

The Mier Park was opened in the 1960s on land between Jana Pawła II Avenue and Marszałkowska Street. In June 1968 a monument to Julian Marchlewski was unveiled there; it was dismantled in 1990. The park was named after the nearby Mier Halls and Mier Barracks, built in the 18th century and named after Wilhelm Mier, commanding officer of the Crown Horse Guard Regiment.

The park takes its name from the Mier Barracks, built in the 18th century and named after Wilhelm Mier, commanding officer of the Crown Horse Guard Regiment stationed there. The nearby Mier Halls and Mier Square carry the same name. The park is also called Downtown Park (Park Śródmiejski) because of its location in the Downtown district.

The park is easily accessible on foot and provides well-maintained paths for strolling through central Warsaw. Visitors can find shaded areas beneath trees as well as open spaces depending on their preferences.

The Feliks Stamm monument, unveiled on 21 May 2019, stands by the East Hall of the Mier Halls, where five Polish boxers won gold at the 1953 European Amateur Boxing Championships. Sculptor Lubomir Grigorov made the monument.
