Saanich Inlet (also Saanich Arm) is a body of salt water that lies between the Saanich Peninsula and the Malahat highlands of Vancouver Island, British Columbia, Canada. Located just northwest of Victoria, the inlet is 25 km (16 mi) long, has a surface area of 67 km2 (26 sq mi), and its maximum depth is 226 m (741 ft). It extends from in the north (separating Salt Spring Island from the Saanich Peninsula) to Squally Reach and Finlayson Arm in the south. The only major tributary feeding the inlet is the Goldstream River.
