Additionally, there was the mountains classification, which did not have a jersey associated with it in 1947. Sixteen mountains were selected by the Tour organisation, divided in two classes. In the first-class mountains, the ten first cyclists received points, with 10 points for the first, 9 for the second, and so forth, to 1 point for the tenth. In the second-class mountains, only the first five cyclists received points, 5 for the first one to 1 for the fifth one. The mountains classification was won by Pierre Brambilla.
