Brazil doesn't have any active volcanoes. However, there are a few extinct volcanoes located in the country, mainly in the Southeastern region. Here are some notable examples:

* The "Pico do Jaraguá" in São Paulo is considered an extinct volcano and is the highest point in the city.

* The "Serra da Mantiqueira" range in the states of São Paulo, Rio de Janeiro, and Minas Gerais, is home to several extinct volcanic formations.

* The "Volcano de Furnas" in the state of Minas Gerais is another extinct volcano, often cited as an example.

It's important to note that the volcanic activity in Brazil occurred millions of years ago and is considered dormant or extinct.
