Cascadero Copper Corporation was a Canadian mining company that focused on the exploration and development of copper and gold deposits in North and South America. The company was founded in 1997 and was headquartered in Vancouver, British Columbia.

Cascadero Copper Corporation's main project was the Toodoggone project, located in northern British Columbia. The project consisted of several mineral claims covering an area of approximately 1,000 square kilometers. The company also had exploration projects in Chile and Argentina.

In 2012, Cascadero Copper Corporation announced that it had entered into an agreement to sell its Toodoggone project to Imperial Metals Corporation. The sale was completed in 2013, and Cascadero Copper Corporation ceased to exist as an independent company.
