Liu Guangdi (18 June 1861 - 28 September 1898) was a Chinese government minister during the late Qing dynasty. He was a leader of the Hundred Days' Reform movement of 1898. After the reforms were reversed in a coup, he and five other leaders were executed. They are now considered as martyrs and are referred to as the Six Gentlemen. Liu was also a reformist patriotic poet of the late Qing Dynasty.
