The 1886 Quebec general election on October 14, 1886, to elect members of the 6th Legislative Assembly for the Province of Quebec, Canada. The Parti National, a broad coalition formed and led by Honoré Mercier, that included the Parti libéral du Québec and nationalist defectors from the Conservative party. The Parti national got a large boost when Liberals and dissident Conservatives rallied in reaction to the hanging of Louis Riel in 1885, for which the federal Conservatives were held responsible by Quebec voters. The nationalists won a majority of seats against the Parti conservateur du Québec, led by John Jones Ross.
The Conservatives hung on in a minority government until Mercier became premier on January 27, 1887.
