Mexikoplatz, Public square in Leopoldstadt district, Vienna, Austria

Mexikoplatz is a public square in Leopoldstadt district that stretches along the southwestern end of the Reichsbrücke bridge near the Danube's banks. The space links different parts of Vienna and is shaped by residential buildings and the Church of St. Francis of Assisi, which anchors the area.

The square was named in 1956 to honor Mexico's protest against Nazi Germany's annexation of Austria at the League of Nations in 1938. Previously, between 1919 and 1934, it was called Volkswehrplatz after the civilian defense forces established following World War I.

The southeastern section of the square features the St Francis of Assisi Church, constructed to mark Emperor Francis Joseph's Golden Crown Jubilee in 1898.

The square is easily reached via the Vorgartenstraße metro station and sits conveniently for connections to other districts. The area is open and well-connected by public transport, making it easy to explore surrounding neighborhoods.

A persistent misconception holds that the square is named after Ferdinand Maximilian, brother of Emperor Franz Joseph, who was once Emperor of Mexico. The name actually honours Mexico's 1938 protest at the League of Nations. From April 2008 to April 2009, Marko Lulić's 3.2-metre steel sculpture of the number 99.73 stood here, referring to the manipulated plebiscite of 10 April 1938.
