Marszałkowska Street (Polish: ulica Marszałkowska), also known by its English name Marshall Street, is one of the main thoroughfares of Warsaw, Poland, located in the district of Downtown (Śródmieście). It runs along the north–south axis, from Bank Square in the north to the Union of Lublin Square in the south.

Contrary to a common urban legend that attributes the name to Marshal of Poland Józef Piłsudski, the street's name actually relates to 18th-century Grand Marshal of the Crown Franciszek Bieliński.^[1][2]

Marszałkowska street was established by Franciszek Bieliński and opened in 1757.^[2] It was much shorter then, running only from Królewska Street to Widok Street.^[3]

The street was almost entirely destroyed during the Warsaw Uprising of 1944.^[3] Rebuilding of Warsaw after World War II coincided with emergence of socialist realism, which greatly influenced the surrounding urban architecture.
