The first European here may have been William Moor in 1747 who sent boat parties about 60 miles up the inlet. In 1762 William Christopher followed the whole inlet to Baker Lake.
The Inuit hamlet of the same name, Chesterfield Inlet, is situated near the waterway's mouth. In previous times, the area was home to Aivilingmiut and Qaernermiut.
