The Sleeping Giant is a series of mesas formed by the erosion of thick, diabase sills on Sibley Peninsula which resembles a giant lying on its back when viewed from the west to north-northwest section of Thunder Bay, Ontario, Canada.

As one moves southward along the shoreline toward Sawyer's Bay the Sleeping Giant starts to separate into its various sections.

Most distinctly in the view from the cliffs at Sawyer's Bay the Giant appears to have an Adam's Apple.

The southernmost point is known as Thunder Cape, depicted by many early Canadian artists such as William Armstrong.
