Varig Flight 820 was a flight of the Brazilian airline Varig that departed from Galeo International Airport in Rio de Janeiro, Brazil, on July 11, 1973, for Orly Airport, in Paris, France. The plane, a Boeing 707, registration PP-VJZ, made an emergency landing on onion fields about four kilometers from Orly Airport, due to smoke in the cabin from a fire in a lavatory. The fire caused 123 deaths; there were only 11 survivors (ten crew members and one passenger).

VARIG (acronym for Viação Aérea RIo-Grandense, Rio Grandean Airways) was the first airline founded in Brazil, in 1927. From 1965 until 1990, it was Brazil's leading airline, and virtually its only international one. In 2005, Varig went into judicial restructuring, and in 2006 it was split into two companies – Flex Linhas Aéreas, informally known as "old" Varig, heir to the original airline – now defunct, and "new" Varig, a new company, fully integrated into Gol Airlines.
