Lorain Swamp is an area of wetlands on the Ewaso Ngiro River in Wajir South, North Eastern Province, Kenya. Little is known about the swamp, due to the hostile terrain and insecurity in the area, it is not protected. The swamp is infested with malarial mosquitos and with vectors of the organisms that cause bilharzia. It is home to crocodiles and is visited by many of the large savannah mammals. Because of the dangers, cattle are not grazed far into the swamp, but they do make extensive use of the shallow waters, particularly in the dry season.
