Bramham Island is an island in the Queen Charlotte Strait region of the Central Coast of British Columbia, Canada, located on the north side of the entrance to that strait. It lies in the entrance to the maze of waterways inland to the northeast, focussed on Seymour Inlet, which includes Belize Inlet and Allison Harbour and Nugent Sound, though it is flanked only by Slingsby Channel, on its north, and by Schooner Channel (formerly Schooner Passage) on its east. To its west is the open waters at the mergence of Queen Charlotte Sound and Queen Charlotte Strait. The island is approximately 23 km2 in size and is mostly low-lying hills and includes a number of freshwater lakes.
