Ryder is a crater on the far side of the Moon. It is located in a patch of higher albedo surface material to the east of the larger Roche-Pauli crater pair. The name for this crater was officially approved at the IAU general assembly in 2006.
This circular-rimmed crater lies along the eastern rim of a larger formation that is most likely the remains of an old, worn impact. Less than a crater diameter to the west of Ryder is the 24-km-diameter satellite crater 'Pauli E'.
