Ha! Ha! River (Saguenay River tributary)

The '''Ha! Ha! River''' is a watercourse in Saguenay–Lac-Saint-Jean, Quebec, Canada.

Its course is entirely located in Saguenay-Lac-Saint-Jean, in the Dubuc provincial constituency and the federal district of Chicoutimi-Le Fjord. The river is shared between the MRC of Le Fjord-du-Saguenay Regional County Municipality (through the town of Ferland-et-Boilleau, Quebec) and the city of Saguenay crossing the La Baie, Quebec borough of Saguenay.

The Ha! Ha! River was badly hit during the Saguenay Flood.

The southern part of Petit lac Ha! Ha! is served by Route 381 to the bridge that marks out the Petit lac Ha! Ha! and Lake Ha! Ha!. This bridge spans the water level at the peninsula attached to the North Shore, then the road heads northwest, serving the northwestern part of the lake Ha! Ha! and the lower part of the Ha! Ha! River Valley.

Forestry is the main economic activity of the sector; recreational tourism activities, second; agriculture is practiced around the lower segment of the river to the urban area (Grande-Baie sector).

The surface of Ha! Ha! River is usually frozen from early December to late March, however, safe ice circulation is generally from mid-December to mid-March.
