Iga Ueno Castle (伊賀上野城, Iga-Ueno-jō^?), also known as Ueno Castle (上野城, Ueno-jō^?) and Hakuho Castle (白鳳城, Hakuhō-jō^?), is a Japanese castle located in Iga, Mie Prefecture, Japan.

Construction on Iga Ueno Castle began in 1585 by the command of Takigawa Katsutoshi. However, the honmaru, or innermost bailey, as well as the tenshu, or donjon, upon which the modern reconstruction was based were built by Katsutoshi's successor, Tsutsui Sadatsugu. Sadatsugu was then succeeded by Tōdō Takatora. Takatora renovated the honmaru, giving it 30 metres (33 yards) high walls. This meant that the walls of the honmaru of Iga Ueno Castle were the tallest of any castle in Japan, a record that still holds. After the threat of rebellion passed, the castle was not seen to be as important as it once was. As a result, the tenshu was not re-built after it was destroyed by high winds in 1612. Because of its beautiful architecture, and floor plan, Iga Ueno Castle is also known as "Hakuho" or "White Phoenix Castle."
