Baie Verte is one of the larger bays of the Northumberland Strait with its northerly limits at Cape Tormentine, a headland located immediately south of the community of Cape Tormentine, and its southerly limits at Aggermore Point, a headland located west of the community of Amherst Shore.

Baie Verte is home to nesting colonies of sea birds and is a nursery area for fin and shell fishes.

Its extensive salt marshes at the western end of the bay create important habitat for wetland animals.

The bay supports several recreational areas, primarily at Amherst Shore Provincial Park, Tidnish Dock Provincial Park, and Fort Gaspareaux National Historic Site of Canada.

The village of Port Elgin is the largest population centre directly fronting the bay.
