Changzhou Island, formerly known in English as Dane or Dane's Island, is an island in the Pearl River Delta of China's Guangdong Province. It is now administered as part of Guangzhou's Huangpu District, although the historic Huangpu Island was nearby Pazhou, which forms part of Haizhu District.
Changzhou is about 11.5 km2 (4.4 sq mi), of which 8.5 km2 (3.3 sq mi) is dry land.
The island was the site of Sun Yat-sen's Whampoa Military Academy (est. 1924) and the 1926 Zhongshan Incident that propelled the academy's commandant Chiang Kai-shek to leadership over the Chinese Nationalists and then all of Warlord China.
Changzhou is now linked to Guangzhou's road network by a bridge to neighboring Xiaoguwei.
