The exact origin of this species is uncertain, but it is thought to be native to large parts of Africa and Asia.
A very widespread species that is naturalised throughout most of Australia, and is particularly common in semi-arid regions. It is widely naturalised in Queensland, New South Wales, South Australia, Western Australia, and the Northern Territory. Also naturalised in ACT and the northern and north-western parts of Victoria.
Wild melon (Citrullus lanatus var. lanatus) is commonly a weed of pastures and agricultural areas, but also grows on floodplains, along river banks, in the centres of dry lakes, in drainage areas, and in disturbed sandy sites. It is currently regarded as a priority environmental weed in one Natural Resource Management region.
The common edible watermelon is a cultivated variant of this species, but it is not widely naturalised or particularly weedy in Australia.
