Frobisher Bay is an inlet of the Davis Strait in the Qikiqtaaluk Region of Nunavut, Canada.

The Bay's funnel like shape ensures that the tidal variance at Iqaluit each day is about 7 to 11 m (23 to 36 ft).

Frobisher Bay's whole coastline is marked with innumerable narrow inlets into which flow many small streams.

The first Church of England service recorded on North American soil was a celebration of Holy Communion at Frobisher Bay in the last days of August or early September 1578.

The Anglican Church of Canada's Prayer Book fixes the day of commemoration as September 3.
