Gaberoun (, alternate spelling Gaberoun, Gaber Awhn, Gabr Awhn, Gabr Own, Gabraun) is an oasis with a large lake in the Idehan Ubari desert region of the Libyan Sahara Desert. Administratively it is located Wadi al Hayaa District and Sabha District of the Fezzan region in southwestern Libya.
A rudimentary tourist camp is located on the northeastern shore, including an open patio, sleeping huts, and a souvenir shop (attended by a Tuareg in full costume) in the winter. The lake is very salty; swimming can be pleasant despite the salt water crustaceans. Mosquitoes are abundant, especially in the summer. October to May is considered the best time to visit as the climate is milder.
