Imandra (Skolt Sami: Âʹvverjäuʹrr, Russian: Имандра, Finnish: Imantero) is a lake in the south-western part of the Kola Peninsula in Murmansk Oblast, Russia, slightly beyond the Arctic Circle.

It is located 127 m above sea level; its area is about 876 km2, maximum depth is 67 m. The shape of the shore line is complicated.

The lake drains into the Kandalaksha Gulf of the White Sea by the Niva River.

The town of Monchegorsk, located on the Monche-Guba inlet in the north-western part of the lake, is known as a centre of winter sports.

Ferries from Monchegorsk would dock in Tik-Guba (today's Apatity), on the main rail line.
