The Rotes Rathaus , Red City Hall) is the town hall of Berlin, located in the Mitte district on Rathausstraße near Alexanderplatz. It is the home to the governing mayor and the government (the Senate of Berlin) of the Federal state of Berlin. The name of the landmark building dates from the facade design with red clinker bricks.

The Rathaus was built between 1861 and 1869 in the style of the north Italian High Renaissance by Hermann Friedrich Waesemann. It was modelled on the Old Town Hall of Toruń, today Poland, while the architecture of the tower is reminiscent of the cathedral tower of Notre-Dame de Laon in France. It replaced several individual buildings dating from the Middle Ages and now occupies an entire city block.
