Beijing National Stadium, also known as the National Stadium,or colloquially as the Bird's Nest, is a stadium in Beijing, China. The stadium was designed for use throughout the 2008 Summer Olympics and Paralympics.

Located in the Olympic Green, the US$423 million stadium is the world's largest steel structure. The design was awarded to a submission from the Swiss architecture firm Herzog  de Meuron in April 2003, after a bidding process that included 13 final submissions. The design, which originated from the study of Chinese ceramics, implemented steel beams in order to hide supports for the retractable roof; giving the stadium the appearance of a Bird's nest. Ironically, the retractable roof was later removed from the design after inspiring the stadium's most recognizable aspect. Ground was broken in December 2003 and the stadium officially opened in June 2008. A shopping mall and a hotel are planned to be constructed to increase use of the stadium, which will host football events after the Olympics.
 

Beijing National Stadium was a joint venture among architects Jacques Herzog and Pierre de Meuron of Herzog de Meuron, project architect Stefan Marbach, artist Ai Weiwei, and CADG which was lead by chief architect Li Xinggang. During their first meeting in 2003, at Basel, the group decided to do something unlike Herzog and de Meuron had traditionally designed. China wanted to have something new for this very important stadium, Li stated. In an effort to design a stadium that was porous while also being a collective building, a public vessel, the team studied Chinese ceramics.This line of thought brought the team to the "nest scheme. The stadium consists of two independent structures, standing 50 feet apart: a red concrete seating bowl and the outer steel frame around it.

Beijing National Stadium hosted the Opening and Closing Ceremonies, athletic events, and football final of the 2008 Summer Olympics, from 8 August to 24 August 2008. The stadium also hosted the Opening and Closing ceremonies and athletic events of the 2008 Summer Paralympics from 6 September to 17 September 2008.Though designed for track field events of the Olympics, the stadium will continue to host sporting events, such as football, afterwards. A shopping mall and a hotel, with rooms overlooking the field, are planned to help increase use after the Olympics. Li stated, This will become the most important public space in Beijing.
