The Katzie are an Indigenous people of the Lower Fraser Valley in British Columbia, Canada. The Katzie historically spoke Halqemeylem, the Upriver Dialect of Halkomelem, one of the Coast Salish family of languages. They are part of the Sto:lo group of peoples, historically referred to as the Fraser River Indians or Fraser Salish. Their band government is the Katzie First Nation, which does not belong to either of the two Sto:lo tribal councils.
Traditional Katzie territory includes the entire Pitt watershed, including the Alouette watershed, the Fraser River and lands adjacent down to Point Roberts, and lands between the Fraser and Boundary Bay. There are approximately 460 members of the Katzie First Nation (their Indian Act-mandated government), but only about 300 live on one of their five reserves.
The Katzie once comprised five communities in the region, each with its own founding chief and which, according to the Katzie, were the foundation of other peoples in the region, notably the Musqueam and Kwantlen. Oe’lecten and his people were based at what is now known as Pitt Lake, Swaneset at Sheridan Hill, Xwoe’pecten at Port Hammond (whose descendants became the Kwantlen), Smakwec at Point Roberts (whose people, the Nicomekl were largely killed in a smallpox epidemic in the 18th century), and C’simlenexw at Point Grey (whose descendents became the Musqueam). Today's Katzie are primarily the descendants of Oe’lecten and Swaneset.
