达令河（英语：Darling River）亦翻作大令河，是澳大利亚第一长河，发源于新南威尔士北部，上游有很多支流；干流向西南流，在温特沃斯（Wentworth）注入墨累河。

水量季节变化很大，干季经常断流，雨季伯克(Bourke)以下可通航。

有一些地理专家将达令河与墨累河下游视为一条3000公里长的单一河流。

The Darling River is the third longest river in Australia, measuring 1,472 kilometres (915 mi) from its source in northern New South Wales to its confluence with the Murray River at Wentworth, New South Wales. Including its longest contiguous tributaries it is 2,844 km (1,767 mi) long, making it the longest river system in Australia.
