Estádio Alfredo de Castilho, known as Alfredo de Castilho or Alfredão, is a multi-use stadium in Bauru, São Paulo, Brazil.

A stadium named after Alfredo de Castilho was built in 1935, honouring an engineer who was the director of NOB (Noroeste de Obras do Brasil) at the time.

[2] It was used until 23 November 1958, when a fire destroyed a part of the stands during a match against São Paulo.

[4] After the fire, Noroeste played at Estádio Antônio Garcia, owned by Bauru Atlético Clube, until the inauguration of Estádio Ubaldo Medeiros on 5 June 1960, in a match against Palmeiras.

[5] The new stadium was later renamed to the original name of Alfredo de Castilho just months later,[2] and purchased by Noroeste in 1986.
