The Tadeusz Kościuszko Monument in Warsaw (Polish: Pomnik Tadeusza Kościuszki w Warszawie) is a statue dedicated to commemorate the national hero of Poland, Lithuania, Belarus, and the United States, general Tadeusz Kościuszko (1746–1817), and situated on the Iron-Gate Square in front of the Lubomirski Palace.

The monument is an exact copy of the Statue of Tadeusz Kościuszko at Lafayette Square in Washington, D.C. unveiled on 9 May 1910, and designed by the Polish sculptor Antoni Popiel (1865–1910).

The bronze elements of the monument were moulded by the Technical Appliance Works at Gliwice.

The copying of the Washington monument was executed by Kraków sculptors Anna and Wojciech Siek.

The monument shows the figure of Tadeusz Kościuszko in the uniform of an American general, holding drawings of the West Point garrison defenses in his hand.
