The Douglas-Daly Experiment Station was an extensive research site of the Northern Territory Administration (NTA) of the Government of Australia and, after statehood, of the Northern Territory Government. It formed part of a string of similar research sites in northern Australia. Located at the junction of the Douglas and Daly Rivers and covering an area of approximately 100 km2, the site spanned three major soil types of the Top End of the Northern Territory — Blain, Tippera and Florina soil types.
