Loughborough Inlet penetrates deep into the Coast Mountain Range of mainland British Columbia, midway between Knight Inlet to the west and Bute Inlet to the east, north of Central Vancouver Island.
The inlet averages 1.6 miles (2.5 km) wide and is approximately 22 miles (35 km) in length from its mouth, where Chancellor Channel and Cordero Channel meet off the north coast of West Thurlow Island, to its head at the mouth of the Stafford River, at the base of Mt. Blake and Mt. Henry.
Loughborough Inlet was name by Captain George Vancouver after Scottish advocate Alexander Wedderburn, first Baron of Loughborough (1733 – 1805), 1st Earl of Rosslyn, and Lord Chancellor of Great Britain from 1793 to 1801.
