Drebbel is a small lunar impact crater named after Cornelius Drebbel that is located to the northeast of the large walled plain Schickard, in the southwestern part of the Moon.

The rim of this crater is roughly circular, with an outward bulge along the east and southeast side.

The west and northwest sides have accumulations along the base where loose material has slumped to the floor.

The remainder of the inner rim is a simple slope that runs down to the interior floor.

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