Cadboro Bay is a bay near the southern tip of Vancouver Island and its adjacent neighbourhood in the municipalities of Saanich and Oak Bay in Greater Victoria, British Columbia, Canada. Cadboro Bay was the site of Sungayka, a village of the Songhees Nation for some 8,000 years prior to the relocation of its people to Victoria's Inner Harbour in the mid 1800s. The land between Gyro Park and Telegraph Bay is included in a Douglas Treaty that is now before the courts. Cadboro Bay takes its name from the first European vessel to enter the bay, the Hudson's Bay Company schooner Cadboro.
