It is between Nunivak Island to its west and Nelson Island and the Alaska mainland to its east. It is demarcated by Cape Etolin to the northwest and Cape Corwin to the southwest (both on Nunivak Island), by Cape Vancouver on Nelson Island to the northeast, and by Cape Avinol on the Alaskan mainland to the southeast.

The strait connects Kuskokwim Bay and the Bering Sea. It is 96 km (60 mi) long and 48–80 km (30-50) miles wide. It is known for strong tidal currents.

Etolin Strait is named after Adolf Etolin, who discovered it and named it Cook Strait. (Etolin was subsequently governor of Russian America from 1840 to 1845.)
