Just for curiosity's sake, the names in Portuguese are: Angola, Brasil, Cabo Verde, Guiné-Bissau, Guiné Equatorial, Moçambique, Portugal, R.A.E. de Macau, São Tomé e Príncipe, Timor-Leste. And the countries/territories where it is unofficial and, therefore, much lesser spoken: África do Sul, Andorra, Bermuda, Damão, Diu e Goa (Índia), Luxemburgo, Namíbia, Uruguai, Zimbábue. Countries/territories next to Brasil also have many Portuguese speakers in the borders, specially: Bolívia, Guiana, Guiana Francesa, Paraguai, Suriname, Venezuela.

Hello Fabizzasso, It is spoken of course in Portugal and Brazil as well as some African countries : Angola, Cape Verde, Guindea-Bissau, Mozambique. It is spoken aslo in São Tomé & Príncipe and is one of the official languages in Equitorial Guinea (with Spanish and French), East Timor (with Tetum), and Macau (with Chinese). It is also widely spoken, although not as an official language, in Namibia, South Africa, Zimbabwe, Daman and Goa India, Luxembourg, Andora, and Bermuda. **So It is the official language ( or at least one of the official languages)of 10 countries: Angola, Brazil, Cape Verde, East Timor, Guinea-Bissau, Equatorial Guinea, Chinese S.A.R. of Macau, Mozambique, Portugal and São Tomé and Príncipe.
