The Portuguese (Portuguese: os Portugueses) are a nation and ethnic group native to the country of Portugal, in the west of the Iberian peninsula of south-west Europe. Their language is Portuguese, and Roman Catholicism is the predominant religion.

Due to the large historical extent of the Portuguese Empire and the colonization of territories in Africa, Asia and the Americas, as well as historical and recent emigration, Portuguese communities can be found in many diverse regions around the globe, and a large Portuguese diaspora exists.

The Portuguese are a southwestern European population, with origins predominantly from Atlantic Europe, Western Europe and the Western Mediterranean.

The earliest modern humans inhabiting Portugal are believed to have been Paleolithic peoples that may have arrived in the Iberian Peninsula as early as 35,000 to 40,000 years ago. Current interpretation of Y-chromosome and mtDNA data suggests that modern-day Portuguese traces largely a significant amount of these lineages to the paleolithic peoples which began arriving to the European continent between the end of the last glaciation around 45,000 years ago.

The following is a list of notable and historically significant people from Portugal.

Gisele Caroline Bündchen (Portuguese pronunciation: [ʒiˈzɛli ˈbĩtʃẽ], German pronunciation: [gi:zɛlə ˈbʏndçn̩]; born 20 July 1980) is a Brazilian fashion model and occasional film actress. She is the goodwill ambassador for the UN Environment Programme. In the late 1990s, Bündchen became the first in a wave of Brazilian models to find international success. In 1999, Vogue magazine dubbed her "The Return of the Sexy Model" and she was credited with ending the "heroin chic" era of modeling. Bündchen was one of Victoria's Secret Angels from 2000 until 2006. Since 2004, she has been the highest-paid model in the world and the sixteenth richest woman in the entertainment industry (as of 2007) with an estimated $150 million fortune.

Models Claudia Schiffer and Naomi Campbell have stated that Bündchen is the only true remaining "supermodel" and according to Forbes she may become the world's first ever billionaire supermodel. In June 2011, Forbes magazine estimated that Bundchen's total earnings over the last 10 years have passed the $250 million mark. As an occasional actress, she had supporting roles in Taxi (2004) and The Devil Wears Prada (2006). From 2000 to 2005, Bündchen was in a much-publicized relationship with American actor Leonardo DiCaprio. She married New England Patriots quarterback Tom Brady in 2009.
