The Tory Channel is one of the drowned valleys that form the Marlborough Sounds in New Zealand.

The Tory Channel is named after one of the pioneer ships that brought British colonists to Wellington in 1840. The channel lies to the south of Arapawa Island, separating it from the mainland. At its western end it joins the larger Queen Charlotte Sound, which it meets halfway along the latter's length. The eastern end of the channel meets Cook Strait close to the strait's narrowest point.

Tory Channel forms a substantial part of the current ferry route between Wellington and Picton. Erosion attributed to the ferries, particularly the new faster ones, has resulted in speed restrictions.

One of the two candidates for easternmost point in the South Island (along with Cape Campbell) lies at the entrance of Tory Channel. Ironically, it is called West Head.
