The Balyktach ( Russian Балыктах ; Yakut Балыктаах , Balyktaach ) is the longest river on the Kotelny Island with 205 km , the largest of the New Siberian Islands in the Arctic Ocean belonging to Russia .

The Balyktach rises in the central part of the island at the northwest end of the Irim-Tas ridge. It flows through the tundra landscape in a first north, then east to south-east direction until it reaches the sandbank called Bungeland , which borders the actual island in the east. Along the western edge of the Bungeland it continues to flow in a south-southwest direction until it finally flows into the Jakow-Smirnizki Bay on the Sannikow Strait in the south of the island with several arms , which connects the Laptev Sea with the East Siberian Sea .

The catchment area of the river covers 4110 km², more than a third of the island area west of the bungland. The most important tributaries are the Tichaja (length 53 km) and the Kustach-Jurjach (83 km) from the left and the Tuor-Jurjach (63 km) and the Glubokaya (69 km) from the right. There are also around 150 lakes in the catchment area. The monthly mean temperatures on the island barely exceed freezing point only in July and August; therefore the Balyktach is frozen over for most of the year.

The uninhabited Kotelny Island, through which the Balyktach flows, belongs to the Sakha Republic (Yakutia) .
