As was the custom since the 1930 Tour de France, the 1956 Tour de France was contested by national and regional teams. Seven national teams were sent, with 10 cyclists each from France, Italy, Belgium, the Netherlands, Spain, Switzerland and Luxembourg/Mixed (the latter a combined team of seven Luxembourgian cyclists added with one Portuguese, on British and one Italian cyclist). France additionally sent five regional teams from 10 cyclists each, divided into North-East/Centre, South-East, West, Île-de-France and South-West. In total, 120 cyclists started the race.
