The Cascadia movement is a collection of various heterogeneous movements seeking greater autonomy for the Pacific Northwest through a political coalition of the U.S. states of Oregon and Washington and the Canadian province of British Columbia. Included in the movements is an independence movement seeking to establish a Cascadian federation, an economic movement for the creation of a single market, a bioregionalist movement for the Cascadia bioregion, and a nationalist or cultural movement for the creation of a Cascadian national identity superseding identification with the state/territory or federal government.
The movement is largely centered in the major cities of Portland, Seattle, and Vancouver, although the bioregion also includes Idaho and the Alaskan Panhandle, along with small parts of California, Montana, Nevada, Utah, Wyoming, and Yukon. More conservative advocates for Cascadian federalism propose borders that include the land west of the crest of the Cascade Range, while some advocates propose borders as far north as Alaska and the Yukon region.
