The Zay (Russian: Зай; Tatar: Зәй) is a river in Russian Federation, a left-bank tributary of the Kama. It is 219 kilometres (136 mi) long, and its drainage basin covers 5,020 square kilometres (1,940 sq mi).[1] It begins near , Leninogorsky District, Tatarstan and falls to the Kama 7 kilometres (4 mi) south-west of Nizhnekamsk.

At its headwaters the river is named the Steppe Zay (Russian: Степной Зай, Stepnoy Zay, Tatar: Дала Зәе). The lower reach of the river after the confluence with , 55 kilometres (34 mi), is named simply Zay. Also, one of headstream Steppe Zay's tributaries is also named Zay. Other major tributaries are the Moshkara, Zay-Karatay, Ursala, Aktashka, and Shumyshka rivers.

The mineralization varies from 2000–3000 to 5000–8000 mg/l. Average sediment deposition at the river mouth per year is 130 millimetres (5.1 in). Drainage is regulated. There are two reservoirs, Zainsk and Karabash Reservoirs constructed in Zay valley.
