- South American citizens do not need a visa;
- European citizens from countries in the Schengen area do not need a visa;
- US/Canadian citizens do need a visa;
- Other countries most likely require a visa.
Please check the official listing of visa requirements for entering Brazil. Wikipedia also has a page on the subject, which you may find useful.
