Kiandra Courthouse, Heritage courthouse in Kosciuszko National Park, Australia.

Kiandra Courthouse is a stone building from the colonial era that stands along the Snowy Mountains Highway. The structure contains the courtroom, a police station, and residential quarters within one integrated complex.

The courthouse and gaol were established as part of Kiandra Township during the gold rush of 1859–60. The original courthouse was the first substantial public building in the town, designed by the office of NSW Colonial Architect James Barnet. In the 1950s and 1960s the building was expanded with timber-clad additions in the Kosciuszko State Park Trust style, and from 1971 to about 1999 it served as the base for the Department of Main Roads' snow clearing operations. It was listed on the NSW State Heritage Register on 2 April 1999 and was severely damaged by fire in the 2020 Kosciuszko National Park bushfires.

Kiandra is regarded as the site of Australia's first ski club and probably the first Australian place to promote snow sports. The 1958 and 1962 chalet extensions, built in Kosciuszko State Park Trust alpine style, later housed people staying for recreation and workers on the Snowy Hydro Scheme.

Access can be challenging due to the remote location and mountain roads, particularly during or after bad weather. Visitors should wear sturdy shoes and allow extra time to explore the site and its surroundings properly.

A mature Western Yellow pine (Pinus ponderosa) survives on the road frontage and marks the courthouse site on the flat landscape. It is the last of three such pines there; the other two were removed after a 2009 inspection because of their deteriorating condition.
