Muṯitjulu is an Indigenous Australian town in the Northern Territory. It is inside Uluṟu-Kata Tjuṯa National Park, just east of Uluṟu. It is named after a knee-shaped waterhole at the base of Uluṟu. Its people are mostly Pitjantjatjara. There are also some Yankunytjnatjara, Luritja and Ngaanyatjarra families living there. Almost everybody works in the national park.
The community had a population of 283 in the 2006 census. It was reported to have dropped to around 150 in 2012, after alcohol was banned.
