Marszałkowska (Marshal Street) is one of the main thoroughfares of Warsaw's city center. It links Bank Square in its north sector with Plac Unii Lubelskiej (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.

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