José Manuel Rodrigues "Joe" Berardo GCIH, ComIH (born 4 July 1944), is a Portuguese and South African businessman, investor, and art collector.

At the age of 18, he emigrated to South Africa where he worked in horticulture distribution and eventually set up large commercial ventures, becoming at the end of the 20th century one of the most renowned and wealthiest Portuguese entrepreneurs.

Berardo's estimated total wealth, including stock in large Portuguese banking and telecommunications companies, was at a time at over €1.9 billion.

[3] Berardo made long-term investments in large companies such as Millennium BCP bank and Portugal Telecom (PT) telecommunications operator, which were both listed on the Euronext Lisbon.

His various collections, which include art deco and Chinese porcelain, encompass more than 40,000 works, of which some 1,200 are by well-known modern and contemporary artists with a reported value of $750 million.

[10] Much as the Spanish state did with the Thyssen-Bornemisza Museum in Madrid,[8] the government agreed to house part of his collection and took a 10-year option to buy 862 paintings and sculptures for 316 million euros, based on a Christie's valuation in 2006.

[9] In 2011, Berardo set up the Aliança Underground Museum, a paid (5€ minimum) exhibition of tiles, ethnographic art, ceramics, minerals and fossils in an unused tunnel on a winemaker's property in Sangalhos.

[9] In 2012, an exhibition of works from Berardo's Modern and contemporary collection, including pieces by Gerhard Richter, Francis Bacon and Andy Warhol, was on show at the Gary Nader Art Centre in Miami, Florida.

[13] Throughout his life, Berardo has been related to several controversial situations that have reached the media: In June 2021, Berardo became a named suspect (arguido status in the Portuguese legal system) and was arrested by members of the Polícia Judiciária for alleged fraud committed against the bank Caixa Geral de Depósitos (CGD) and a number of other financial crimes.
