A Polish Brazilian is a Brazilian person of full or partial Polish ancestry, who is aware of such ancestry and remains connected, in some degree, to Polish culture, or a Polish-born person permanently residing in Brazil. The number of Polish descendants in Brazil is estimated at 1.8 million. Also, a Polish Brazilian can be a child of a Brazilian mother and Polish father (and vice versa).
