| Eponym | Hippalus |
Hippalus the remnant of a lunar crater on the eastern edge of Mare Humorum. To the southeast is the Campanus crater, and to the northwest is the small flooded Loewy crater.
The southwest rim of the crater is missing, and the crater forms a bay along the edge of the mare. The surviving rim is worn and eroded, forming a low, circular mountain range. The lava-flooded floor of Hippalus is bisected by a wide rille belonging to the Rimae Hippalus. This rille follows a course to the south before curving gently to the southwest for a total length of 240 kilometers. The crater floor to the east of this rille is more rugged than the area in the western half.

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 Hippalus crater.
