Quercus garryana, the Garry oak, Oregon white oak or Oregon oak, is a tree species with a range stretching from southern California to southwestern British Columbia. It grows from sea level to 210 meters (690 ft) altitude in the northern part of its range, and at 300 to 1,800 meters (980 to 5,910 ft) in the south of the range in California. The tree is named after Nicholas Garry, deputy governor of the Hudson's Bay Company, 1822–35.
In British Columbia, the Garry oak grows on the Gulf Islands and southeastern Vancouver Island, from west of Victoria along the east side of the island up to the Campbell River area. There are also small populations along the Fraser River on the British Columbia mainland.
In Washington state, the garry oak grows on the west side of the Cascade Range, particularly in the Puget Sound lowlands, the northeastern Olympic Peninsula, Whidbey Island and the San Juan Islands. It also grows in the foothills of the southeastern Cascades and along the Columbia River Gorge.
In Oregon, the Garry oak grows on the west side of the Cascade Range, primarily in the Willamette, Umpqua and Rogue River valleys, and along the Columbia River Gorge.
In California, the garryana variety grows in the foothills of the Siskiyou and Klamath Mountains, the Coast Ranges of Northern California, and of the west slope of the Cascades. The semota variety grows in the Sierra Nevada and Coast Ranges as far south as Los Angeles County.
