Torchefelon (French pronunciation: [tɔʁʃəfəlɔ̃]) is a commune in the Isère department in southeastern France.

[3] Torchefelon is in what was the ancient territory of the Allobroges, a group of Gallic tribes occupying the former Savoy, as well as the part of Dauphiné, located north of the river Isère.

The castle of Ponteray once stood in the town, but it was burned by Thibaud de Rougemont the Archbishop of Vienne and there are no remains.

[1] There is a kind of micro-climate, in the town of Torchefelon generally as a colder climate than the plain of Bourgoin.

It is therefore not uncommon in winter to find snow in the sector of this town while the rest of Nord-Isère is devoid of it.
