The King Leopold Ranges are a range of hills in the western Kimberley region of Western Australia. The range was named on 6 June 1879 by the explorer Alexander Forrest, during an expedition in the Kimberley area, after King Leopold II of Belgium, "for the great interest taken by His Majesty in exploration".Crossed by the Gibb River Road about 134 kilometres east of Derby, part of the ranges are covered by the 3,921 square kilometres King Leopold Ranges Conservation Park, managed by the Department of Parks and Wildlife. The ranges separate the main Kimberley plateau from the southern Fitzroy plains and consist of quartz sandstone intruded by dolerite.
The ranges are shaped like a crescent with a length of 567 kilometres running from the northern end of the Durack Range in the East to east of Secure Bay in the West Kimberley.
