Estádio Joaquim Américo Guimarães, commonly referred to as Arena da Baixada, is a football stadium in the Água Verde neighborhood of Curitiba, Paraná. Opened in 1914, it is the home stadium of Atlético Paranaense, who also own and operate it. The stadium will be one of the host venues for the 2014 FIFA World Cup.

Ever since renovation works were completed in June 1999, the historic Estádio Joaquim Américo has been considered one of Brazil's most modern and best-appointed stadiums. It came as no surprise, therefore, that the home ground of Atlético Paranaense, which was originally constructed back in 1914, was among those venues chosen to host games at the 2014 FIFA World Cup.
