Purple Bamboo Park (Chinese: ; pinyin: Zǐ Zhú Yuàn Gōngyuán; also called Zizhuyuan Park or Black Bamboo Park) is one of the seven largest parks in Beijing, China. It is located in the Haidian District of northwestern Beijing. The park consist of three connecting lakes covering over a total area of 48 hectares. Earth dredged from the lakes was pilled up to form several small hills on the lakes' eastern shore to complement the natural hills that line the lakes' western shores.
There are five bridges connecting the lakes, islands and hills into a single integrated area. To the north of the lakes the Changhe River flows through. Typical of classical Chinese gardening style, and like many of Beijing's parks and gardens, it is a mountain-water landscaped garden. Constructed around canals and large lakes, the Bamboo Park is known for its liberal use of verdant bamboo groves. The garden has a variety of bamboos on display, with the variety ranging as much as up to 50 species. There is also an art museum located within the park.
During the 2008 Summer Olympics, it was selected as one of the three protest zones.
