Harbour Air Seaplanes is a scheduled floatplane service, tour and charter airline based in Richmond, British Columbia, Canada. The predominantly seaplane airline specializes in routes between Vancouver, Nanaimo, Victoria, Sechelt, Comox, Whistler and the Gulf Islands, primarily with de Havilland Canada floatplanes. Harbour Air operates de Havilland Beavers, Otters and Twin Otters.

A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call floatplanes "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats.
