Abitibi-Ouest is a provincial electoral district in the Abitibi-Témiscamingue region of Quebec, Canada, that elects members to the National Assembly of Quebec.

It notably includes the municipalities of Amos, La Sarre, Macamic, Barraute, Palmarolle, Trécesson, Sainte-Germaine-Boulé and Dupuy.

The riding was created for the 1944 election from a part of Abitibi.

In the change from the 2001 to the 2011 electoral map, Abitibi-Ouest gained the municipality of Barraute, as well as the part of the unorganized territory of Lac-Despinassy that it did not already have, from Abitibi-Est.
