Fort Nelson is a community in northeast British Columbia, Canada within the Northern Rockies Regional Municipality (NRRM). It held town status prior to February 6, 2009 when it amalgamated with the former Northern Rockies Regional District to form the NRRM, becoming its administrative centre. The NRRM is the first regional municipality in the province.
The community lies east of the northern Rocky Mountains in the Peace River region along the Alaska Highway at mile 300. Fort Nelson is home to 3,902 residents, representing 70% of the NRRM's total population of 5,578.
The majority of Fort Nelson's economic activity has historically been concentrated in the energy and tourism industries, and until very recently, forestry. The forests surrounding Fort Nelson are part of Canada's boreal forest. Fort Nelson is on the southwest edge of the Greater Sierra oil & gas field.
