德塞阿多河是阿根廷的河流，位于圣克鲁斯省，河道全长615公里，集水区面积14,450平方公里，发源自布宜诺斯艾利斯湖，最终注入大西洋。

Deseado River (Spanish:Río Deseado) is a river in the Argentine province of Santa Cruz. The name Deseado comes from the English Desire, the name of one of the two ships commanded by John Davis during the Thomas Cavendish expedition of 1592.

The river is born from the glacier-thaw Buenos Aires Lake on the northwestern part of the province at the Andes range, and travels for 615 kilometres (382 mi) before reaching the Atlantic Coast. On its way southeast, its water is tapped for irrigation. Its tributaries include the Pinturas River and the Fénix River.
