Johannes Adrianus "Jan" Janssen is a Dutch former professional cyclist (1962–1972). He was world champion and winner of the Tour de France and the Vuelta a España, the first Dutch rider to win either. He rode the Tour de France eight times and finished all but the first time. He won seven stages and wore the yellow jersey for two days. He was easily spotted in the peloton because of his blond hair and his glasses. As of the death of Federico Bahamontes in August 2023, he is, after Lucien Aimar, who won in 1966, the oldest surviving winner of the Tour de France.
