Flamsteed is a small lunar crater located on the Oceanus Procellarum. It lies almost due east of the dark-hued Grimaldi basin, and north-northwest of the flooded Letronne crater bay on the south edge of the mare.

The rim of this crater is not circular in form, having a bulging rim to the southeast. The interior is relatively flat and undistinguished by impacts. The crater lies within the southern rim of a crater that has been almost completely submerged by the basaltic-lava flows that formed the Oceanus Procellarum. All that remains of this feature designated 'Flamsteed P' are some low ridges and hills arranged in a circular formation.

The Surveyor 1 craft landed within the northeast rim of the buried 'Flamsteed P' feature, about 50 kilometers north-northeast of the Flamsteed crater rim.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Flamsteed crater.
