Lockhart River was originally an Anglican mission, at the site now known as the 'Old Site' approximately 60 kms from where Lockhart River community is today. Five different clan groups were forcibly moved into the area in 1924 to establish the mission. Difficulty in getting supplies through meant that a town plan was developed and the community moved to the present site in the sixties.

The Lockhart River airport was established during World War II, as a bomber base. There were three airstrips, and thousands of American and Australian troops were stationed here. During the Battle of the Coral Sea, many sorties against the Japanese departed from here.
