Pan-Indianism is a philosophy and movement promoting unity among different American Indian groups in the Americas regardless of tribal or local affiliations. Some academics use the term pan-Amerindianism as a form of disambiguation from other territories called Indian. The movement is largely associated with Native Americans in the Continental United States, but has spread to other indigenous groups as well. A parallel growth of the concept has occurred in Alaska and Canada. There, however, other indigenous peoples, such as the Inuit and the Métis are often included in a wider rubric, sometimes called pan-Aboriginal or some variation thereof.
Pan-Indian organizations seek to pool the resources of indigenous groups in order to protect the interests of native peoples across the world.
