The Gulf Islands are the islands in the Strait of Georgia, between Vancouver Island and the mainland of British Columbia, Canada.According to BC Geographical Names (BCGNIS) the name "Gulf Islands" was originally intended and commonly understood to refer to the archipelago at the southern end of the Strait of Georgia—from Gabriola Island in the north to Saturna Island in the southeast and D'Arcy Island in the southwest. During the 1990s, however, the name began to be applied to all the islands in the Strait of Georgia, resulting in the introduction of the term "Southern Gulf Islands", which BCGNIS calls a misnomer, to distinguish the original "Gulf Islands" from the rest, which are sometimes called the "North Gulf Islands". BCGNIS further notes that Quadra Island is increasingly described as the "northernmost of the Gulf Islands".
