Gill Airways was an airline based at Newcastle Airport in the United Kingdom. Its ICAO callsign was Gillair, with IATA Airline Designator 9C and ICAO airline code GIL.

Founded in 1969, the airline originally operated as Gill Aviation, mainly providing cargo and mail flights for various companies including the British Royal Mail. Following the acquisition of passenger aircraft in June 1989, the airline changed its name to Gill Air. The arrival of Fokker 100 aircraft in 1995 resulted in the airline entering into a codeshare agreement with Air France between Newcastle upon Tyne and Paris Charles de Gaulle airport. The title of Gill Airways was adopted in 1995, to reflect the growing importance of passenger operations to the airline.

After emerging from administration in 2000, the airline seemed to have a promising future ahead of it. However, following the events of September 11th 2001, the principle financier, the Bank of Scotland, withdrew funding. The final day of operations was September 20th 2001, with the airline placed into liquidation and the loss of 240 jobs.
