Route 307 is a provincial road located in the Outaouais region of Quebec.

The road runs mostly parallel to the Gatineau River on the eastern side of it.

The main communities the highway passes through are Gatineau, Cantley and Val-des-Monts.

In Gatineau, it is known as Rue Saint-Louis, in Cantley it is known as Montée de la Source and in Val-des Monts it is named Route Principale.

On June 23, 2010, part of the highway was closed between Val-des-Bois and Bowman, due to a partial bridge collapse caused by a 5.0 magnitude earthquake.
