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.
Today, Cadboro Bay also gives its name to the neighbourhood situated between the bay itself and the University of Victoria, bounded by the Uplands district to the south, Ten Mile Point to the east and the Queenswood neighbourhood to the north. At the heart of the neighbourhood is the local centre, Cadboro Bay Village.
A prominent resident of the neighbourhood in the first half of the 20th century was Frank V. Hobbs. His brother, Edwin, bought land in Cadboro Bay for a dairy farm, while Frank Hobbs engaged in business in Victoria and other parts of Vancouver Island. Upon the death of Edwin, Frank moved to Cadboro Bay, and became active in municipal politics and on the Victoria School Board. He was influential in expanding the provision of high schools for greater Victoria. In recognition of this and other services he provided to the area, the local elementary school, opened in 1951, was named in his honour.
