The Natives' Society of Newfoundland refers to several, now defunct, non-denominational organizations in Newfoundland established to protect the rights and privileges of Newfoundland-born citizens against the flood of newcomers to the island in the mid-nineteenth century. The societies' official mandate was to advance the careers and interests of native-born Newfoundlanders, regardless of ethnic origin or religious affiliation, and marked the arrival of a new phenomenon, Newfoundland nationalism. Natives' Societies existed in St. John's, Harbour Grace and Carbonear as well as possibly other communities.
