Lavoisier is a lunar impact crater that is located near the northwestern limb of the Moon, at the western edge of the Oceanus Procellarum.

Due south of Lavoisier is the disintegrated crater Ulugh Beigh.

The interior of this floor-fractured crater is notable for the curving ridge that parallels the northwestern inner wall.

The remainder of this circular form can be traced out across the interior by an intermittent pattern of lower-albedo surface that is concentric with the inner wall.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lavoisier.
