Roger Hassenforder (23 July 1930 in Sausheim 3 January 2021 in Colmar) was a French professional racing cyclist from Alsace.
Hassenforder was a professional cyclist from 1952 to 1965. He was known as the joker of the pack, earning him the nickname "boute-en-train". He was known for his interviews during the course. His major victories as cyclist were in the Tour de France, but he did not win much in other races. His best years were 1955-1959, when he won eight stages in the Tour and wore the yellow jersey for four days.
After his cycling career ended, he opened a restaurant in Kaysersberg, that was a favourite meeting place for cycling fans in the 1960s, and is still run by the Hassenforder family.
