The arm Henriette (English: Henriette's arm) is a tributary of the Bras de Jacob, flowing in the southern part of the city of Saguenay, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. The course of the Henriette arm crosses the northwest part of the zec Mars-Moulin.

The small valley of the Bras Henriette is served by some secondary forest roads, especially for the needs of forestry and recreational tourism activities.^[1]

Forestry is the main economic activity in this valley; recreational tourism, second.

The surface of the Henriette arm is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.
