Mr Lauda, who was hospitalised in January for about 10 days while suffering from influenza, died yesterday surrounded by family, according to a family statement published by Austrian media.
"His unique achievements as an athlete and entrepreneur are and will remain unforgettable, his tireless zest for action, his straightforwardness and his courage remain a role model and a benchmark for all of us, he was a loving and caring husband, father and grandfather away from the public, and he will be missed," the statement added.
Tributes poured in for the Austrian, who was called a "legend" by British racing driver Jenson Button.
He tweeted: "A legend has left us. Rest in peace Niki."
Niki Lauda won three world titles in 1975, 1977 and 1984 with Mercedes and Ferrari.

He made a miraculous recovery despite horrific burns and finished second in the championship to James Hunt.
He went on to win two of his three titles as well as becoming a prominent figure in the aviation industry.
