The Lower Mainland is a geographic and cultural region of the mainland coast of British Columbia that generally comprises the regional districts of Metro Vancouver and the Fraser Valley. Home to approximately 3.05 million people as of the 2021 Canadian census, the Lower Mainland contains sixteen of the province's 30 most populous municipalities and approximately 60% of the province's total population.

The region was historically occupied by the Sto:lo, a Halkomelem-speaking people of the Coast Salish linguistic and cultural grouping.
