The Inya (Russian: Иня́, pronounced [ɪˈnʲæ]) is a river in Kemerovo and Novosibirsk Oblasts of Russia.

[2] The river flows through a rather densely populated area, and is crossed by several railway lines.

The Inya has its sources in a ridge in the central part of the Kuznetsk Basin, and flows through Kemerovo Olast in a mainly westerly direction, then enters Novosibirsk Oblast and finally joins the Ob, just 5 kilometres (3 mi) southeast of downtown Novosibirsk.

At the village of Beryosovka, some 30 kilometres (19 mi) from its mouth, the river's average discharge is 470 cubic metres per second (17,000 cu ft/s).

The river freezes over in the beginning of November, and stays frozen till the spring thaw starts in mid-April.
