The 2B11 is a 120 mm mortar developed by the Soviet Union in 1981 and subsequently fielded in the Soviet Army.

The basic design for the 2B11 was taken from the classic Model 1943 120 mm mortar, and incorporated changes to make the mortar less heavy.

It is being supplemented in Russia by the new 2B24 82 mm mortar.

Some countries have developed self-propelled versions of the 2B11: This article relating to artillery is a stub.
