The Arga-Sala (Russian: Арга-Сала; Yakut: Арҕаа Салаа, Arğaa Salaa) is a river in Yakutia (Sakha Republic) and Krasnoyarsk Krai, Russia.

Its sources are in the northeastern slopes of the Bukochan Range, Central Siberian Plateau, in the Evenkiysky District of Krasnoyarsk Krai.

The Arga-Sala flows roughly eastwards with rapids and riffles in numerous stretches.

It flows then across a floodplain with small lakes, changing direction with southeastward and northeastward bends, but still within a generally eastward trend.

[2] Taimen, lenok, whitefish, grayling and pike are the main fish species found in the waters of the Arga-Sala.
