Estádio Olímpico João Havelange

The Estádio Olímpico João Havelange (English: João Havelange Olympic Stadium) is a multi-use stadium located in the neighbourhood of Engenho de Dentro in Rio de Janeiro, Brazil. It is used mostly for football matches and athletics and is the home field of the football club Botafogo. The stadium will be an athletics venue for the 2016 Summer Olympics and 2016 Summer Paralympics.

The stadium is known by a number of names. The nickname Engenhão ([ẽʒẽˈɲɐ̃w̃]) refers to the location of the stadium. Since 2015 the Rio municipality has allowed Botafogo to refer to the stadium as Estádio Nilton Santos (English: Nilton Santos Stadium). The name honors Nilton Santos, regarded as one of the greatest defenders in the history of the game and a member of the World Team of the 20th Century. Botafogo attempted to have the official name of the stadium change but this was rejected.

The stadium was built by a consortium under the leadership of Odebrecht S.A..

The stadium is scheduled to host the athletics competitions at the 2016 Summer Olympics and the 2016 Summer Paralympics. Structural problems in the roof were identified in March 2013 that caused the stadium to be closed for repair. The stadium's capacity is intended to be increased to 60,000 for the Games.
