Kiyosu Castle (清洲城, Kiyosu-jō) is a Japanese castle located in Kiyosu, western Aichi Prefecture, Japan. It is noted for its association with the rise to power of the Sengoku period warlord Oda Nobunaga. The kanji in the name of the castle was written as 清須城. The current partial reconstruction dates to 1989 and was built as a centennial celebration for the modern-day city of Kiyosu.
