The Újpest Water Tower (Hungarian: Újpesti víztorony) is one of many water towers in Budapest.
The Újpest Water Tower played an important role in World War II. Explosives were stored within the tower, possibly reserved for its later destruction. In December 1944, Hungarian partisans ambushed the Arrow Cross guards and seized the ammunition, thus preventing the tower from being destroyed. Had it been destroyed, the entire area would have been left without water.
