The Col d'Iseran was first used in the Tour de France bicycle race in 1938.
The first rider over the summit was Felicien Vervaecke but on the descent he was passed by Gino Bartali.
Bartali had taken the leader's yellow jersey from Vervaecke the previous day and retained it to the finish in Paris.

The first mountain time trial was introduced to the Tour in 1939.
It went over the Col d'Iseran from Bonneval-sur-Arc to Bourg-Saint-Maurice and was won by Sylvere Maes by four minutes.

The pass has been used five times on the Tour de France since 1947.
It was scheduled to be used in 1996 but was left out at the last minute due to bad weather.
As a result of snow on both the Col de l'Iseran and the Col du Galibier the scheduled 190 km (118 mi) stage from Val-d'Isère to Sestriere in Italy was truncated to a 46 km (29 mi) sprint from Le-Monetier-les-Bains.
Bjarne Riis claimed the sprint, resulting in him taking the yellow jersey which he retained to the finish in Paris.

Col de l'Iseran was crossed in 2007 in stage 9, which started from Val-d'Isère and went 159.5 km (99 mi) to Briançon on 17 July.
The Tour crossed the climb once again in the 2019 edition, in Stage 19 to Tignes.
However, due to adverse weather conditions on the ascent to Tignes, the stage was truncated with times for the general classification being taken at the summit of the Col de l'Iseran.
