Arab Brazilians are Brazilian citizens of Arab ethnic, cultural, linguistic heritage and identity. The majority of Arab Brazilians trace their origin to the Levantine region of the Arab World, known in Arabic as Bilad al-Sham, primarily from Lebanon and Syria, as well as Palestine. Arab Brazilians are Christians in the great majority. The first Syrians and Lebanese arrived in São Paulo around 1880. It is not known exactly when, although the Syrians and Lebanese say that in 1885 there was a small core of peddlers working in the market square. By 1920, the census listed 50,246 Syrians and Lebanese in Brazil, 38.4% (2/5) of these in the state of São Paulo. The 1940 census enumerated 48,614 Syrians, Lebanese and other related groups with a decrease of approximately 1647 people. As immigration almost ceased after 1929 and the colony aged, it is surprising that the decline was not even greater. The trend of the period between 1920 and 1940 was the continuous concentration of Syrians and Lebanese in São Paulo. Almost half (49.3%) of Syrians and Lebanese residents in Brazil lived in São Paulo.

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.
