The de Havilland Canada DHC-5 Buffalo is a short takeoff and landing (STOL) utility transport, a turboprop aircraft developed from the earlier piston-powered DHC-4 Caribou. The aircraft has extraordinary STOL performance and is able to take off in distances much shorter than even light aircraft can manage.

On February 24, 2006, Viking Air of Victoria, British Columbia, a manufacturer of replacement parts for all out-of-production de Havilland Canada aircraft, purchased the type certificates from Bombardier Aerospace for all versions of the DHC-1 through DHC-7 series aircraft, giving Viking exclusive rights to manufacture and sell new aircraft of those types. In December 2008, Viking Air indicated their intention to put the Buffalo series back into production at their home factory in Victoria, British Columbia or in Calgary, Alberta. The new production Buffalo features Pratt & Whitney Canada PW150 turboprops, a glass cockpit, enhanced vision and night vision goggle capability. The company intends to propose the aircraft as a replacement for the RCAF fleet of existing DHC-5As, and says it has received extensive interest in the type, including several letters of intent for the DHC-5NG.
