Zhan Yuan (simplified Chinese: 詹园; traditional Chinese: 詹園; pinyin: Zhānyuán; Jyutping: Zim1jyun4), also known as Zhongshan Grand Mansion Gate, is a modern Chinese garden designed in a Suzhou and Hangzhou-derived style spanning the Beixi River (北溪河) near Huzhou Mountain (湖洲山) in the south of Zhongshan in Guangdong Province, China.

[2][3] At multiple hectares it is billed as the largest private Chinese garden in the Lingnan area of southern China,[4] and is officially classed as a National AAAA class tourist attraction, the second highest classification.

It is not fully traditional, for example Australian Callistemon dominate in place of willows, and ornamental imports such as Ravenala madagascariensis are broadly distributed.

[citation needed] The garden, over 100 acres (40 ha) was established 1998 by Huang Yuanxin (黃遠新) for his aged mother, and in 2003 opened to the public.

The garden was later expanded by constructing the second northern section, gifted to his father.
