Mungo National Park is an isolated national park in Australia in the Balranald Shire, NSW. It is part of the Willandra Lakes Region, a World Heritage Site covering 2,400 square kilometres, and incorporating seventeen dry lakes.

The central feature of Mungo National Park is Lake Mungo, the second largest of the ancient dry lakes. Mungo National Park is most significant for the archeological remains which have been discovered there. The remains of Mungo Man, the oldest human remains discovered in Australia, and Mungo Lady, the oldest known human to have been ritually cremated, were both discovered within the park. They were buried on the shore of Lake Mungo, beneath the 'Walls of China', a series of lunettes on the South eastern edge of the lake.

Wildlife abounds. Species ranging from red and western grey kangaroos, echidnas, native mice and bats, lizards and of course a few species of snakes are found. The birdlife is prolific including emus, orange chats, pink cockatoos, falcons and other birds of prey.
