West Nodaway River is a stream in southwest of the U.S. states of Iowa. It is a tributary of Nodaway River and is 73.5 miles long. The stream is monitored at Clarinda, Iowa by the NOAA.

The West Nodaway River arises from the hills of southwest Iowa about 8 miles northeast of Massena. It begins traveling southerly for about 8 miles then its course changes to be southwesterly as it heads towards Grant, which it passes to the southeast. Then the river continues south alongside US 71, with much of it being channelized as it heads towards Villisca, but a few miles before reaching Villisca, it is fed by Viking Lake of Viking Lake State Park from Dunns Creek. After almost 16 miles, the stream passes Villisca to the west and joins with the Middle Nodaway River. 10 miles further south it reaches Clarinda, the largest town in the Nodaway River watershed. The West Nodaway continues southerly another 7 miles south and passes Shambaugh to the east before joining with the East Nodaway River about 4.3 miles north of the Iowa-Missouri border.
