The Guangxu Emperor (August 14, 1871 – November 14, 1908), personal name Zaitian, is the eleventh Emperor of the Qing dynasty, and the ninth Qing emperor to rule over China proper.

His reign lasted from 1875 to 1908, but in practice he ruled, without Empress Dowager Cixi's influence, only from 1889 to 1898.

He initiates the Hundred Days' Reform, but is abruptly stopped when the empress dowager launches a coup in 1898, after which he is put under house arrest until his death.

His regnal name, "Guangxu", means "glorious succession".
