Renfrew Airport was the former domestic airport serving the city of Glasgow until it was decommissioned in 1966. It was located in the Newmains area of Renfrew, approximately 2 kilometres east of Abbotsinch Airfield which would eventually replace it. It consisted of a main terminal building and ancillary buildings, and a main runway which ran west south-west of the terminal. Already in existence as a military facility during the First World War, it first handled scheduled flights in 1933 with the first regular destination being Campbeltown.
