The Okanagan (), also known as the Okanagan Valley and sometimes as the Okanagan Country, is a region in the Canadian province of British Columbia defined by the basin of Okanagan Lake and the Canadian portion of the Okanagan River. It is part of the Okanagan Country, extending into the United States as Okanogan County in north-central Washington. According to the 2016 Canadian census, the region's population is 362,258. The primary city is Kelowna.
The region is known for its dry, sunny climate, dry landscapes and lakeshore communities and particular lifestyle. The economy is retirement and commercial-recreation based, with outdoor activities such as boating and watersports, skiing and hiking. Agriculture has been focused primarily on fruit orchards, with a recent shift in focus to vineyards and wine.
The region stretches northwards via the Spallumcheen Valley to connect to Sicamous in the Shuswap Country, and reaches south of the Canada–United States border, where it continues as Okanagan Country. The Okanagan as a region is sometimes described as including the Boundary, Similkameen and Shuswap regions, though this is because of proximity and historic and commercial ties with those areas.
