里弗斯利（英语：Riversleigh）是位于澳大利亚昆士兰州西北部格雷戈里河（Gregory River）畔的著名化石点。此地有从渐新世到中新世的各种古代哺乳动物、鸟类和爬行动物化石。

里弗斯利的化石都十分稀有，许多淡水中的柔软石灰岩层都完好地保存了下来，而没有被地质运动压扁。 这意味着许多化石都是三维立体的。

自1901年开始有在当地发现化石的记录， 主要发掘活动始于1963年。1973年开始有系统地发掘。 1994年作为波特加姆拉国家公园的延伸部份登陆世界遗产。

Riversleigh, in the north-west of Queensland, is Australia's most famous fossil site. The 100 km area has fossil remains of ancient mammals, birds and reptiles of Oligocene and Miocene age.

The fossils at Riversleigh are rare because they are found in soft freshwater limestone which has not been compressed. This means the animal remains retain their three-dimensional structure. The area is located within the catchment of the Gregory River.
