Prince Charles Island is a large, low-lying island with an area of 9,521 km² (3,676 sq mi), making it the world's 78th largest island and the 19th largest island in Canada. It is located in Foxe Basin, off the west coast of Baffin Island, in the Qikiqtaaluk Region of Nunavut, Canada. Despite the island's size, it wasn't discovered until 1932, when the tug captain W. A. Poole first sighted it. His information never made it onto any published map. It was rediscovered in 1948 by Albert-Ernest Tomkinson navigating an RCAF Avro Lancaster, though it was likely known to the local Inuit long before that. The island was named for Prince Charles, who was born the same year.
