Uki ( YEW-ky) is a village situated near Mount Warning in the Tweed Valley of far northern New South Wales, Australia in the Tweed Shire. At the 2006 census, Uki had a population of 203 people. The town's name may have derived from an aboriginal word for "small water plant (like a fern) with a yellow flower and edible root".
There are several stories, almost certainly apocryphal, associated with the origins of the name. One is that timber cutters, who were the first non-Aboriginal settlers in the area, marked the finest cedar for export to the United Kingdom with "UK1", this eventually becoming UKI, or Uki as it is known today.
There are three approaches to Uki village; from the North it is approximately 15 minutes by road south of the main township of Murwillumbah along the Kyogle Road and 4 km past the turnoff to the World Heritage listed Mount Warning National Park, from the South West along the Kyogle Road from Lismore, Kyogle and Nimbin and from the East along Smiths Creek Road linking Uki to the village of Stokers Siding and the Tweed Valley Way to coastal towns including Brunswick Heads and Byron Bay. It is also possible to travel to Mullumbimby from Uki using gravel back roads and fire trails through the Mount Jerusalem National Park.
Clarrie Hall Dam is located 10 km from Uki, and the area is described as "one of New South Wales’ finest fishing destinations". While the main function of the Dam is to provide fresh water for the Tweed Shire, recreational activities include sailing, rowing, canoeing, bass fishing, picnicking, bush hiking and bird watching.
