The New Westminster Land District is one of 59 land districts of British Columbia, Canada, which are the underlying cadastral divisions of that province, created with rest of those on Mainland British Columbia via the Lands Act of the Colony of British Columbia in 1860. The British Columbia government's BC Names system, a subdivision of GeoBC, defines a land district as "a territorial division with legally defined boundaries for administrative purposes" All land titles and surveys use the Land District system as the primary point of reference, and entries in BC Names for placenames and geographical objects are so listed.
This land district is named for the city of New Westminster, which at the time of its creation was the capital of the Mainland Colony. Greater Vancouver, the Fraser Valley, the Sunshine Coast and the Highway 99 corridor up to and including the Resort Municipality of Whistler, are all within this land district, as well as Savary, Raza, and East and West Redonda Islands. Also included are the settlements of Skookumchuck Hot Springs (Skatin) and Port Douglas on the lower Lillooet River, Long Island, which is a large island in the middle or Harrison Lake, and the Village of Harrison Hot Springs, the western half of the District of Kent, and almost all of City of Chilliwack.
