This is a list of aircraft produced or proposed by the Lockheed Aircraft Corporation from its founding as the Lockheed Aircraft Company in 1926 to its merging with Martin Marietta to form the Lockheed Martin Corporation in 1995.

Ordered by model number, Lockheed gave most of its aircraft astronomical names, from the first Vega to the C-5 Galaxy. Aircraft models listed in italics and with higher numbers – 780 following 80 and preceding 81, for example – are variants or developments of the base model.
