Olympic Sports Centre Stadium (simplified Chinese: 奥体中心体育场; traditional Chinese: 奧體中心體育場; pinyin: Ào Tǐ Zhōngxīn Tǐyùchǎng) is a multi-purpose stadium in Beijing, China. It is currently used mostly for football matches. It was constructed in 1990 for the Asian Games held that year. It was renovated to host the 2008 Summer Olympics, where it hosted football matches and the running and riding parts of the modern pentathlon events. For the riding discipline, the football field at the core of the venue has been turned into a high-standard temporary equestrian field. The renovation also added four pavilion-styled rotating rampways around the stadium.
The stadium has a floor space of 34,975 square metres, which exceeds the original building area of 20,000 square metres. Its capacity has doubled after the renovation, from about 18,000 to 36,228.
