State Highway 84 (SH 84) is a South Island state highway in New Zealand. It connects the holiday resort town of Wanaka to State Highway 6, the main north-south highway servicing the western part of the South Island.
Known as Wanaka Luggate Highway, it is a two-lane road for its entire length. The road begins at SH 6 to the south of Albert Town and proceeds in a westerly direction past Puzzling World to descend into the township of Wanaka.
Before being re-gazetted as SH 84 in 1998, the road formed part of State Highway 89, more well known as the Crown Range Road.
