加拿大地盾（英语：Canadian Shield）是北美大陆，从加拿大中部延伸到北部的前寒武纪（约45亿年前 - 5.4亿年前）古岩盘。大致上围绕哈德逊湾，是非常稳定的地盘。

The Canadian Shield, also called the Laurentian Plateau, or Bouclier Canadien (French), is a large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (North American or Laurentia craton). Composed of igneous rock resulting from its long volcanic history, the area is covered by a thin layer of soil. With a deep, common, joined bedrock region in Eastern and central Canada, it stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada; it also extends south into the northern reaches of the United States. Human population is sparse, and industrial development is minimal, while mining is prevalent.
