The Bajoran outback is a remote area of Bajor.
In 2372, Benjamin Sisko and Kasidy Yates planned to spend three days in the Bajoran outback. Sisko asked Jake Sisko to come with them but Jake declined, as he had fallen under the influence of the entity known as Onaya. (DS9 episode: "The Muse")
Jake once commented that Elim Garak's shop on Deep Space 9 seemed to sell everything from formal dinner attire to clothing that could be used on an expedition to the Bajoran outback. (DS9 novel: Cardassian Imps)
