The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, is the second-largest known impact crater or astrobleme on Earth, as well as one of the oldest.. The basin is located on the Canadian Shield in the city of Greater Sudbury, former municipalities of Rayside-Balfour, Valley East and Capreol lie.

The belt is exposed principally along the southeastern margin of the Canadian Shield, but inliers occur in the Appalachians, the East Greenland Caledonides, Texas, and Mexico.

The Sudbury Basin in the Canadian Shield has been proposed as a meteorite impact site subsequently deformed by endogenic tectonism. Detailed study of the structural geology strengthens this hypothesis and strongly suggests that the deformation of the basin was coeval with major folding and flattening ( to b.y.
