The Fraser River Port Authority is a federally mandated port authority operating under the Canada Marine Act. It administers Fraser Port, a major deep-sea port located on the main arm of the Fraser River, downstream from Kanaka Creek and Pitt Lake to the Strait of Georgia. The purpose of the Port is to facilitate economic development and trade.

Under one name or another, the Port Authority has been the custodian of Fraser Port since 1913. At present, its functions are to administer property within its jurisdiction, which includes land covered by water as well as some upland sites, overseeing the harbour and maintaining the channel, facilitating international trade through its marine terminals, and providing environmental stewardship.
