# List of former counties of Quebec

Historical counties and territories in Quebec, Canada, and their county seats are listed below. The list is alphabetized by county, but can also be alphabetized by seat.
In terms of internal division, there are four types of counties:
* Those that contain only townships, as do counties surveyed by the British after 1763.
* Those that contain only parishes, as do counties chiefly in the Saint Lawrence Valley settled by French colonists before 1761.
* Those that each contain both townships and parishes.
* Those that each contain townships and undivided lands, as do the northern counties outside the main populated areas of the province.
Parishes as a land unit division arise from the elevation of municipalities based on religious parish limits (parish municipalities). Quebec's counties were dissolved in the early 1980s and Quebec was then divided into regional county municipalities.
