Xiangshan County, also spelled Hsiangshan, Siangshan, Heungsan, and Heungshan, was a former county in Southern China. Since 1912, it was a county in Kwangtung Province ("Guangdong"), in the Republic of China. It was renamed Zhongshan County (then usually romanized "Chungshan") in April 1925, in honor of the founder of the Republic of China, Sun Yat Sen, a Xiangshan native.
