The De Havilland DH-114 Heron was a British twin-engine, low-wing aircraft designed for regional air travel, first introduced in 1950. It was based on the earlier De Havilland DH-104 Dove but with improvements in capacity and performance, making it suitable for commercial airlines and private use. The Heron was designed to serve routes that required aircraft capable of carrying more passengers than the Dove but still operate from smaller airports with shorter runways.

With its all-metal construction and distinctive streamlined fuselage, the DH-114 Heron provided a comfortable and efficient alternative to larger airliners for short to medium-range flights. It was particularly useful for smaller airlines and regional carriers, thanks to its combination of reliability and performance in challenging conditions.
