Lake Malawi National Park is a national park at the southern end of Lake Malawi in Malawi, Southeast Africa. It is the only national park in Malawi that was created with the purpose of protecting fish and aquatic habitats. Despite this being its main purpose, Lake Malawi National Park includes a fair amount of land, including a headland, the foreshore and several small rocky islands in Lake Malawi.
