Italian Brazilians are Brazilians of full or partial Italian descent, whose ancestors were Italians who emigrated to Brazil during the Italian diaspora, or more recent Italian-born people who've settled in Brazil. Italian Brazilians are the largest number of people with full or partial Italian ancestry outside Italy, with São Paulo being the most populous city with Italian ancestry in the world. Nowadays, it is possible to find millions of descendants of Italians, from the southeastern state of Minas Gerais to the southernmost state of Rio Grande do Sul, with the majority living in São Paulo state. Small southern Brazilian towns, such as Nova Veneza, have as much as 95% of their population of Italian descent.

Brazilians are the citizens of Brazil. A Brazilian can also be a person born abroad to a Brazilian parent or legal guardian as well as a person who acquired Brazilian citizenship. Brazil is a multiethnic society, which means that it is home to people of many ethnic origins, and there is no correlation between one's stock and their Brazilian identity.
