Madawaska-la-Vallée was a provincial electoral district which elected one member to the Legislative Assembly (MLA) of New Brunswick, Canada.

Its only MLA was Progressive Conservative Party of New Brunswick representation Percy Mockler, now a member of the Senate of Canada.

In 2006, most of the district was merged with Restigouche West to form Restigouche-la-Vallée.

* This was a new riding created largely out of a merger of the former ridings of Madawaska Centre and Madawaska South, the former of which was held by Clavette, a Liberal and the latter of which was held by Mockler, a Progressive Conservative.
