São João da Barra (Portuguese pronunciation: [sɐ̃w ʒuˈɐ̃w dɐ ˈbaʁɐ, - ˈʒwɐ̃w -]) is a municipality located in the Brazilian state of Rio de Janeiro.

[3] Until the arrival of the Portuguese in Brazil in the 16th century, the entire region of the mouth of the Paraíba do Sul River was occupied by the Goitacá Indians.

In the 18th century, the village became an important crossing point for sugar from Campos dos Goytacazes towards Salvador.

On 17 June 1850, the village was elevated to city status by decree of the Brazilian emperor Dom Pedro II.
