One theory is that the name "Curitiba" comes from the Tupi words kurí tyba, "many pine seeds" due to the large number of pinecones of Paraná pines in the region prior to its founding.
Another version, also using words from the Tupi language, is that it originates in the combination of kurit (pine tree) and yba (large amount).

The Portuguese, who founded a settlement on the site in 1693, named it "Vila da Nossa Senhora da Luz dos Pinhais" (Village of "Our Lady of the Light" of the Pines).
The name was changed to "Curitiba" in 1721.
Curitiba officially became a town in 1812, spelling its name as "Curityba."
An alternative spelling was "Coritiba."
This was used in press and state documents.
A state decree in 1919 settled the dispute by adopting "Curitiba."
