Titius is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb.

It lies to the west of the Lacus Solitudinis, a small lunar mare.

The rim of this crater has been nearly ruined by subsequent impacts, leaving only the northern and northeast parts relatively intact.

The interior floor has some irregularities, but is relatively featureless and level to the northeast.

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