Spencer Jones is a lunar impact crater on the Moon's far side.

The interior floor is relatively level with a low ridge offset to the south of the midpoint.

Attached to the southwestern outer rim is the small satellite crater Spencer Jones Q.

Just over 20 km from Spencer Jones is the slightly smaller crater Papaleksi to the south-southwest.

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