Okanagan-Westside was a provincial electoral district for the Legislative Assembly of British Columbia, Canada from 2001 to 2009.
It included the small cities of Westbank, Westside, Peachland, and Summerland, and extended from the city limit of Summerland (in the south) to the Okanagan Lake bridge, in Westside (north).
The area of this constituency was first settled in the late 19th and early 20th centuries by European agriculturalists.
The Okanogan peoples, an Interior Salish language group, have settled the area for several thousand years.
This electoral district was carved out of Okanagan West, Okanagan-Vernon and Okanagan-Penticton.
