Lake Nero (Russian: Не́ро) is a shallow, highly eutrophic lake in Yaroslavl Oblast, Russia. The lake has an area of 54.4 km², a maximum length of 13 km, width 8 km and depth 3.6 m. The bottom of the lake is covered with thick layer of silt sapropel (a sort of ooze used as fertilizer and for other purposes).

The lake is estimated to be about 500 thousand years old, making it one of a few pre-ice age lakes in central Russia.

The first people settled at the lake at 6 thousand years ago. It is historically certain that the Merya tribe had their capital in Sarskoe Gorodishche on the southern shore of the lake. They named the lake Nero (meaning "silty", "marshland") or Kaovo ("place where gulls live").

In the 9th Century ast Slavs came to the lake. They called the lake Rostovian Lake in the honor of town Rostov.

There are two islands in Nero: Levsky (Russian: Левский, meaning "Forest Island") and Rozhdestvenskij (Russian: Рождественский, meaning "Christmas Island"). The latter is also known as Gorodskoj(Russian: Городской, meaning "City Island"). This island formed a pre-ice age monolith. Flowing into Nero Lake are eight rivers (Sara (Russian: Сара), Ishnya (Russian: Ишня), Kuchibosh (Russian: Кучибош), Mazikha (Russian: Мазиха), Varus (Russian: Варус), Chucherka (Russian: Чучерка), Unitsa (Russian: Уница), Sula (Russian: Сула) etc.), one flows out (Veksa (Russian: Векса)).
