Rabbitkettle Hot Springs is a naturally occurring hot spring located in the Northwest Territories of Canada. The springs are found in the Nahanni National Park Reserve, along the South Nahanni River. Rabbitkettle Hot Springs are situated on a limestone plateau and comprise two large travertine mounds. At 20 metres (66 ft) high and 70 m (230 ft) in diameter, the free-standing North Mound is the largest travertine mound in Canada. The South Mound has grown into a nearby hillside and is not as tall. They are the only tufa mounds in the world known to be located on permafrost. The mounds are multi-coloured and tiered.
The name Rabbitkettle comes from the Dene word gahnhthah, meaning "kettle". The translation was adopted by English-speaking locals as "Rabbitkettle", from the peculiar shapes of the basins in the area. The springs were considered a sacred place to the Dene, who left offerings such as tobacco to ensure good fortune.
