The Kargat (Russian: Каргат) is a river in Novosibirsk Oblast, Russia.

[1] The river begins in the southern sections of the Vasyugan Swamp, at 143 metres (469 ft) above sea level and flows in a southwesterly direction over the Baraba Steppe roughly parallel to the Chulym River.

Finally it joins the left bank of the Chulym at an elevation of 110 metres (360 ft), shortly before its mouth in lake Malye Chany.

[2] A significant part of its waters either evaporates or is infiltrated in the ground, and the average discharge at the village of Nizhny Kargat, 36 kilometres (22 mi) from its mouth, is just 8.54 cubic metres per second (302 cu ft/s).

Here the river is crossed by the Trans-Siberian Railway and the M51 highway.
