The Perikian Peninsula was a location on Bajor at the southern end of one of the continents.
In ancient times, the peninsula was originally controlled by the Lerrit; rebels tired of their oppressive nature rose up and took the peninsula and its port, Natlar for themselves.
The peninsula was divided from the mainland by a series of hills, and jutted into the Korvale Ocean. Boats approaching from the west would have to traverse a corner and not come into sight of the port until it was almost ready to dock.
The peninsula was named for the woman who first openly spoke of rebelling from the Lerrit, Periki Remarro. (DS9 short story: "Horn and Ivory")
During the Occupation of Bajor the Cardassians had an internment camp on the peninsula. (STO mission: "First Contact Day")
