In the United States and Canada, a pioneer cemetery is a cemetery that is the burial place for pioneers in any area subject to territorial expansion, with founding dates spanning from the late 18th to early 20th centuries.
The State of Nebraska defines an "abandoned or neglected pioneer cemetery" as having been founded or situated upon land that "was given, granted, donated, sold, or deeded to the founders of the cemetery prior to January 1, 1900", and that "contains the grave or graves of a person or persons who were homesteaders, immigrants from a foreign nation, prairie farmers, pioneers, sodbusters, first generation Nebraskans, or Civil War veterans".
The State of Oregon defines a "pioneer cemetery" as "any burial place that contains the remains of one or more persons who died before February 14, 1909", which is the 50th anniversary of Oregon's statehood.
California recognizes that pioneer cemeteries may have become the responsibility of a public cemetery district or may be dedicated by the city or county as a pioneer memorial park if no longer maintained. The law also authorizes the "removal of such copings, improvements, and embellishments which the governing board finds to be a threat or danger to the health, safety, comfort, or welfare of the public."
Dates are of official founding or earliest burial.
