The Avro Canada C102 Jetliner was a Canadian prototype medium-range turbojet-powered jet airliner built by Avro Canada in 1949. It was beaten to the air by only 13 days by the de Havilland Comet, thereby becoming the second purpose-built jet airliner in the world, while both were preceded by the Nene Lancastrian, and the Nene Viking, both of which were conversions of piston engine airliners. The name "Jetliner" was chosen as a shortening of the term "jet airliner", a term which is still in popular usage. The aircraft was considered suitable for busy routes along the US eastern seaboard and garnered intense interest, notably from Howard Hughes who even offered to start production under license. However, continued delays in Avro Canada's all-weather interceptor project, the CF-100 Canuck, led to an order to stop working on the project in 1951, with the prototype Jetliner later cut up for scrap.

A jet airliner or jetliner is an airliner powered by jet engines. Airliners usually have two or four jet engines; three-engined designs were popular in the 1970s but are less common today. Airliners are commonly classified as either the large wide-body aircraft, medium narrow-body aircraft and smaller regional jet.
