The list of regions of Canada is a summary of geographical areas on a hierarchy that ranges from national (groups of provinces and territories) at the top to local regions and sub regions of provinces at the bottom. Administrative regions that rank below a province and above a municipality are also included if they have a comprehensive range of functions compared to the limited functions of specialized government agencies. Some provinces and groups of provinces are also quasi administrative regions at the federal level for purposes such as representation in the Senate of Canada. However regional municipalities (or regional districts in British Columbia) are included with local municipalities in the article List of municipalities in Canada.

An inter provincial region includes more than one province or territory but does not usually include the entirety of each province or territory in the group. However, the geographic or cultural features that characterize this type of region can sometimes lead to the relevant provinces or territories being seen as regional groups like British Columbia Yukon and Alberta Northwest Territories.

National Capital Region, a federal administrative region that straddles the Ottawa River on the Ontario Quebec border and includes the cities of Ottawa and Gatineau.

The provinces and territories are nearly all sub divided into regions for a variety of official and unofficial purposes. The geographic regions are largely unofficial and therefore somewhat open to interpretation. In some cases, the primary regions are separated by identifiable transition zones, particularly in Alberta, Saskatchewan, and Ontario. The largest provinces can be divided into a number of primary geographic regions of comparatively large size (e. g. southern Ontario), and subdivided into a greater number of smaller secondary regions (e. g. southwestern Ontario). The primary and secondary regions in Ontario are mainly non administrative in nature. However, they tend to be defined as geographic groupings of counties, regional municipalities, and territorial districts, so that the regions are defined by a system or collection of borders that have local administrative importance. In other large provinces, the primary and secondary geographic regions are defined more strictly by topographical and ecological boundaries. In geographically diverse provinces, the secondary regions can be further subdivided into numerous local regions and even sub regions. British Columbia has a much greater number of local regions and sub regions than the other provinces and territories due to its mountainous terrain where almost every populated lake, sound, and river valley, and every populated cape and cluster of small islands can claim a distinct geographical identity. At the other extreme, Prince Edward Island is not divided into any widely recognized geographic regions or sub regions because of its very small size and lack of large rivers or rugged terrain. New Brunswick's small size renders it dividable into local geographic regions only. Several provinces and territories also have supra municipal administrative regions. Their borders mostly do not harmonize with the geographic regions, so they are not considered subdivisions or groupings of the latter.
